Most riders searching for the best aftermarket motorcycle exhausts are not chasing a dyno number, they are chasing one specific outcome: more sound character and less weight without a trip to the machine shop. The shortlist below covers ten slip-on canisters, model-specific full systems and mid pipes that real buyers have installed and rated, and the specs and fitment notes come straight from the product data rather than from marketing copy.
There is a reason this roundup looks different from a shop-window list of titanium MotoGP pedigree systems. Riders on forums keep asking the same practical question, whether it will clear the center stand, will the O2 sensor port line up, does it need welding, and honest answers beat brand prestige every time. An FZ09.org thread is a good example: someone ordered a full carbon system precisely because the maker stated the low-level routing was designed to clear a center stand.
One counter-consensus is worth stating before the picks. A thread on r/motorcycles arguing that factory exhausts sound great makes the case that OEM pipes plus intake sound can beat aftermarket pipes that end up too throaty, and the OEM silencer tone on the Meteor and Speedmaster is repeatedly praised for exactly that reason. You are not obliged to change anything, but if you do, you now know which sound you are running away from.
What follows covers ten components in order of usefulness for a first or second upgrade: a quick top three, a side-by-side table, a segment list of which brands suit which bike type, one full section per product, then the buying guide covering slip-on versus full system, materials, tuning, fitment and legality. If you are starting out on a small-displacement machine, our kids electric motorcycle guide covers the same entry-level logic for a different class of bike.

Best Exhaust Brands by Bike Type
Match the brand to the machine before you match the brand to the budget. Riders searching for the best motorcycle exhaust brands consistently split into segment clusters, so here is where each of the major names actually belongs.
Sportbikes and supersports: Akrapovic and Yoshimura lead this segment, with the Yoshimura RS-3 Works Race cited as the benchmark for mid-range pull and a deep growl.
MotoGP and track pedigree: SC-Project is the pick riders name when the question is pure sound, and it holds up in that role. Akrapovic is usually conceded as the performance leader.
Cruisers and V-twins: Vance and Hines, Bassani, Cobra and Freedom Performance cover this group, and the Shortshots Staggered is the widely cited cruiser example.
Dirt and off-road: FMF and Pro Circuit are the reference points, and for mini bikes and pit bikes the JFG RACING and STONEMEN systems in this roundup do the same job at a fraction of the cost.
Entry-level and small-displacement: Fast Pro, Arrow, LeoVince and universal canisters such as the LEIMO KPARTS and POSENG models here cover the bikes that most riders start on.
Note what the premium tiers buy and what they do not. A titanium full system from a MotoGP supplier is a lighter, better-sounding, better-made part, and it is also a part that needs a fuel map on a modern fuel-injected engine. The components in this roundup are the sensible first step on most machines.
1. LEIMO KPARTS Universal Carbon-Look Slip-On – Most Reviewed Universal Can Here
Motorcycle Slip On Muffler,1.5-2″ Carbon Fiber Unversal Slip on Silencers
★★★★★★★★★★38-51mm universal fit
Removable DB killer
365mm carbon-look body
1.37 kg aluminum and stainless
- Widest fitment range in the roundup at 38mm to 51mm
- Welded stainless adapter arrives pre-fitted
- Removable DB killer switches loud and quiet
- 969 ratings means fitment data is plentiful
- 4.1 average is tied lowest here
- Carbon-look coating is aluminum not real carbon fiber
- Some bikes need a fabricated mounting bracket
This is the can I would put on a bike nobody has made a model-specific part for. The welded stainless steel adapter is factory fitted and covers 38mm through 51mm, which means the same part works on a 70cc pit bike header and a larger street machine without a trip to the welder.
At 365mm overall length and 1.37 kg it carries the lowest listed weight in this roundup, and the 1.5 inch inlet with a 5.1 cm outlet covers the most common slip-on geometry. The hexagonal shape is deliberate, because tip geometry is what drives the perceived tone.
Where the 4.1 average comes from is worth being straight about. The five-star share is 60% and one-star reviews sit near 9%, so the complaints concentrate on fitment and finish expectation rather than outright failure, and the finish being a coating over aluminum rather than true carbon is the single most repeated note.
One buyer-reported pattern is worth repeating: the 1.5 inch inlet and 5.1 cm outlet work on a surprising number of bikes without an adapter, which is not obvious from a universal-fit label. The 90-day manufacturer warranty is the shortest cover here, so treat the first few rides as a shakedown period.
Because the can is a slip-on, your headers and catalytic converter stay in place. That means the change is almost entirely acoustic and cosmetic, and it means the part can come off in under ten minutes if you decide it is not for you.
What it fits and how it installs?
Anything with a 38mm to 51mm pipe: dirt bikes, street bikes, scooters, quads and small ATVs. Springs, hooks, clamps and the pre-installed adapter are all included, so most installs are a clamp-and-spring job from the side of the bike.
Buyers on non-standard brackets report needing light fabrication, so if your mounting point is unusual, budget an hour and a drill. Everything else fits first time.
Who should skip it?
Skip it if you are chasing a specific deep-throat note and cannot tolerate a tipy character, or if you need a part that carries proper street certification paperwork. It is also not a full system, so it will not change how your engine breathes above the midrange.
Budget riders starting out on small machines can see the same fit-first logic in our kids electric motorcycle picks before they size their first exhaust.

2. Fast Pro Universal Hex Muffler – Tie-Best Value at 4.4
Universal 1.5-2″ Inlet Hexagon Exhaust Muffler Pipe Slip On Scooter Motorcycle ATV Dirt Street Bike
★★★★★★★★★★38-51mm clamp range
390mm hex canister
Aluminum, stainless and titanium
3.3 lb
- 4.4 average across 740 reviews
- 73% five-star share
- 38-51mm clamp range covers most small and mid bikes
- Mounting hardware included
- Installation instructions are not included
- Heaviest listed weight of the universal cans here
- Small tail of fitment complaints
The Fast Pro hex can is the one I recommend when someone asks for a single part that fits a lot of bikes and does not need explaining. The connection diameter spans 38mm to 51mm and the 390mm length gives the exhaust gas enough volume to settle into a lower note than a very short can. Its 4.4 average is tied at the top of this roundup, and it arrives as a complete bolt-on with the mounting hardware already in the box.
Material specification is unusual at this level, listing aluminum, stainless steel and titanium in the construction rather than a single coated tube. It is a 1.5 inch inlet hexagon with a 3.3 lb listed weight, which is heavier than the other universal cans here and worth remembering on a small frame.
Buyer data backs the rating. Seventy-three percent of reviews are five-star with 740 ratings, and the recurring theme is a no-frills bolt-on that works on dirt bikes, scooters and ATVs without fuss.
Owner part number F17130008 and the hexagonal shape are both consistent across the listing, and with 740 ratings it is the second-heavily reviewed can here. That volume of real installs is what makes the 4.4 figure meaningful rather than a sample of four.
The one practical caution is weight. At 3.3 lb this can is heavier than the other universal models in this group, and on a pit bike or a lightweight minibike a lighter can is the better starting point. On a street bike you will never notice the difference.
Where the ratings come from?
The 6% one-star share is mostly fitment and documentation rather than noise or tone. Owners consistently report that the clamp range covers more bikes than they expected, and that the hardware in the box is enough for a basic install.
Because instructions are not included, budget extra time to work out the spring orientation and bracket position yourself. It is a fifteen minute job once you know it, and a frustrating hour if you do not.
Who should skip it?
Skip it if your bike is a lightweight minibike where every pound matters, since 3.3 lb is heavier than the other universal cans listed here. It is also the wrong pick if you want deep sound and this can only be opened up by changing the baffle arrangement, which this model does not offer.

3. JFG RACING Dirt Bike Full Slip-On – Defined Fitment Instead of Guessing
JFG RACING Dirt Bike Full Slip On Exhaust for HAWK 250 CRF230F CRF150F TBR7
★★★★★★★★★★38mm slip-on and outlet
Honda CRF150F and CRF230F 2003-2017
Hawk 250 and TaoTao TBR7
Round canister
- Model-specific fitment on listed bikes
- 4.4 average across 499 reviews
- 69% five-star share
- Recognizable design for small dirt bikes
- Only fits the listed models and years
- Costs more than the universal cans
- Bracket fabrication can be needed on unlisted frames
JFG RACING makes the case for a model-specific part better than any universal can can. If you own a CRF150F or CRF230F from the 2003-2017 run, a Hawk 250 or a TaoTao TBR7, the 38mm inlet and 38mm outlet geometry is defined rather than adapted.
The result is a 4.4 average across 499 reviews, with 69% of those at five stars and only 2% at two stars, one of the tightest distributions in this roundup. Buyers mention good fit, improved sound and appearance in roughly equal measure.
Compared with a universal can on the same bike, you are trading flexibility for predictability. That is the right trade when the bike is a daily rider and you do not want to measure pipe diameters on a Sunday afternoon.
Model-year coverage from 2003 through 2017 is unusually long for a model-specific part, and it means the system can follow a bike through most of its early life without a second purchase.
The round canister profile is a deliberate style choice over the hexagonal cans elsewhere in this roundup, and several owners mention that appearance is as large a factor as sound. Manufacturer part number Y17130205 covers the listed platforms.
Which bikes it covers?
The listing names the CRF150F and CRF230F for 2003-2017, the Hawk 250 and the TaoTao TBR7, and it is positioned as a complete slip-on system rather than a loose canister. Aluminum, stainless steel and titanium are listed in the material specification with a round canister profile.
If your bike is not on that list, this is the wrong part and one of the cheaper universal cans is a better use of your time. JFG systems on unlisted frames can need bracket fabrication, which is where the small tail of complaints comes from.
Who should skip it?
Skip it if you own anything outside the named platforms, or if your build is a one-off custom frame with no matching mount point. A round 38mm canister is not a universal solution even when the bolt pattern looks close.

4. STONEMEN Full Exhaust System for CRF150F and CRF230F – Complete Header to Muffler
STONEMEN Full Exhaust Muffler System Slip On For CRF150F CRF230F 2003-2013 Titanium
★★★★★★★★★★Full system with 430mm muffler
304 stainless pipe
2003-2013 CRF150F and CRF230F
3.1 kg
- Replaces the entire tract
- measurably quieter than the factory muffler
- 304 stainless pipe with a 6061-T6 aluminum can
- 4.2 average across 308 reviews
- Thin stainless pipe is hard to weld
- Loose mid-pipe joints often need sealant
- 9% one-star reviews
This is a full system rather than a slip-on: a complete exhaust from header to muffler instead of a canister that bolts onto a factory link pipe. On the correct bike it is measurably quieter than the OEM muffler it replaces, which is the opposite of what most people assume an upgrade will do.
Construction is 304 stainless steel pipe with a 6061-T6 aluminum muffler, a 430mm muffler length and a 38mm connection, weighing 3.1 kg. Fitment is listed for 2003-2013 CRF230F and 2003-2013 CRF150F with a three-month warranty.
The straight-through design is why the noise drops. Owners of these small minibikes report restoring throttle response and gaining back some of the low-end that a small engine loses through a restrictive OEM canister, and several fit it to ATC and Chinese mini bikes after modest fabrication.
Because this is a full system rather than a slip-on, it does change how the engine breathes, and on a small carbureted or early fuel-injected engine that difference is much easier to live with than on a modern fuel-injected platform. No fuel map is part of this recommendation.
Buyers also note the can sits lower than some OEM units, which matters on small bikes where the rear wheel and brake stay close to the exhaust. Model YG20160331-EM007 is the full system, and both a three-month guarantee and seller support are included.
What to know before you fit it?
Two mechanical details cause most of the friction. The stainless pipe is thin-gauge and hard to MIG weld if you want to modify anything, and the joints between header, mid pipe and muffler sit loose enough that many installers end up using sealant.
There is also no projecting pipe at the muffler joint, so there is nowhere for a hose clamp to bite and the seal depends on sealant. If you are not comfortable with sealant work, allow extra time or budget a mechanic.
Who should skip it?
Skip it if you want the aggressive tone most riders chase, because the straight-through design here is built to move gas quietly rather than shout. It is also model-locked to 2003-2013 CRF platforms, so check your year twice.

5. FVRITO Exhaust Kit for 125cc Pit Bikes – Complete Head Pipe and Muffler Set
FVRITO Exhaust Pipe Muffler Silencer Kit for 125cc 110cc 70cc Dirt Pit Bike, 28mm Muffler for Chinese XR50 CRF50 Coolster SSR Baja Taotao Atomik Thumpstar Roketa Apollo Motorcycle ATV Parts Black
★★★★★★★★★★70cc-125cc pit and dirt bikes
28mm head with 45mm spacing
Double-layer stainless walls
1.41 kg
- Head pipe and muffler in one box
- Double-layer stainless walls damp vibration and noise
- Broad Chinese minibike compatibility
- Deeper resonant note for small pit bikes
- Only fits 28mm 70cc-125cc applications
- Will not fit Honda models beyond CRF50 and XR50
- Interface size must be checked before ordering
The FVRITO kit is the most complete package here, running from the exhaust manifold through to the tailpipe in one box. That matters on a small pit bike, because buying a head pipe and a muffler separately means two separate orders and two sets of gaskets to line up.
It covers 70cc, 110cc and 125cc pit and dirt bikes with a 28mm head, 45mm between ends, and a double-layer stainless inner wall designed to damp vibration and absorb noise. Weight is 1.41 kg and the warranty is 90 days.
Compatibility is broad on paper: CRF50, XR50 and CRF50F plus Coolster, SSR, Atomik, Baja, Taotao, Thumpstar, Apollo, Kayo, Roketa and Lifan. The box includes the muffler, head pipe, metal clip, rubber gasket, two gaskets and a screw kit, so nothing is missing at install time.
Everything needed for the install is in the box, which is the rarest thing in this roundup. Most universal canisters ship with springs and clamps; this one also includes the head pipe, so there is no second part to source and no gasket to buy separately.
At 1.41 kg it is one of the lighter complete systems here, and the available blue, red and black variants mean the colour does not have to be black. Manufacturer part number PQG028-ZT-Black with a 90-day warranty.
Sound character on a small engine
The double-wall construction is the reason the note reads as resonant rather than thin, and buyers describe a deeper and louder exhaust sound on small pit bikes. The removable pipe guard lets you change the look and the heat exposure at the tailpipe.
It is worth remembering how small these engines are. A 125cc single makes different exhaust gas pulses than a 500cc twin, so a system that sounds thin on a bigger bike can sound full here, and the opposite is also true.
Who should skip it?
Skip it if your bike is not a 28mm head, because the fitment is narrow by design. It also will not fit Honda models other than the CRF50, XR50 and CRF50F, which rules out a lot of small Hondas people assume are covered.

6. POSENG Lengthened Universal Muffler – Deeper Tone From a Bigger Can
POSENG 1.5-2″ Inlet Motorcycle Exhaust Muffler Slip On 400mm Lengthened Universal for Dirt Bike ATV Street Bike 38-51mm Inlet with DB Killer Silencer HTRACING (Grilled Blue)
★★★★★★★★★★395mm lengthened body
38-51mm slip-on fit
Removable DB killer
Titanium alloy and stainless
- Longer 395mm body than most 38-51mm cans here
- Built-in removable DB killer
- Titanium alloy and stainless resists corrosion
- Distinctive baked blue gradient finish
- Color is a four-color gradient not a single tone
- One-star share near 11%
- Cosmetic listing gives less fitment detail
Can length is one of the least expensive sound upgrades available, and the POSENG can is the clearest example in this roundup. At 395mm overall it is longer than most 38-51mm cans of the same inlet range, and extra volume before the tip is what turns a thin buzz into a fuller note.
It fits a 38-51mm slip-on connection with a 1.5 inch inlet and 2 inch outlet, weighs 1.76 kg, and is built from titanium alloy and stainless steel. The built-in removable DB killer lets you choose a deeper, quieter note or a louder, sharper one with the same part.
The finish is the talking point visually. It is a double-head baked blue process producing a red, blue, yellow and silver gradient, which is not what the Grilled Blue name suggests, so expect a multi-tone tip rather than a single color.
Model number MP-1045-J76-CS covers the listed configuration, and the package includes one muffler with the DB killer plus the mounting accessories. At 1.76 kg it sits in the middle of the weight range in this roundup.
The trade is simple: you give up colour choice and a small amount of fitment detail, and you get a longer can with a sound adjustment built into the same part. For many riders that is a better exchange than picking the most polished listing.
Who it suits and when?
Buyers like the deeper tone the 395mm body delivers and the ability to open it up on larger engines when they want more. It is a good choice on a street bike, scooter, dirt bike or ATV where a 38mm to 51mm clamp is the only thing you can rely on.
Because the listing is cosmetic-forward, fitment detail is thinner than the model-specific systems elsewhere in this roundup. Measure your pipe before ordering and check the 38-51mm range rather than assuming.
Who should skip it?
Skip it if a uniform finish matters to your build, since the gradient cannot be changed. It is also a poor choice if you want the quietest possible system, because the whole point of the part is the extra volume and you only get the quiet version with the baffle fitted.

7. Sporacingrts Stainless Steel Muffler – Retro Tail Cone With Three Adapters
Sporacingrts Stainless Steel Motorcycle Exhaust Muffler Silver
★★★★★★★★★★37-45mm adjustable inlet
Three supplied adapters
Retro tail cone
1.91 kg
- Adjustable 37-45mm inlet from three adapters
- Slimmer and shorter than many factory mufflers
- Chrome finish suits retro and cruiser builds
- Mounts on either side of the bike
- Weak clamp hardware and poor washers
- Insert spacer does not fully seal the joint
- Rust reported despite the stainless description
This is the most polarizing part in the roundup and the one most often adapted to bikes outside its nominal fitment. Owners report a big improvement over heavy OEM mufflers on Royal Enfield, Triumph, Harley and Continental GT650 builds, restoring midrange and cutting weight.
The differentiator is the inlet. It comes with three interchangeable adapters at 42mm, 39mm and 37mm against a 45mm inlet, giving a 37-45mm range that is unusual at this level, and it can mount on either side of the motorcycle.
Against that, a smaller group reports weak clamps, an unsealed slip-on joint and rapid rusting of the underlying base metal despite the stainless description. At 4.1 across 156 ratings with 8% one-star reviews, the split is real rather than noise.
Model number YMX3-1-TP155-W is the part, and the retro tail cone is a deliberate styling reference rather than a modern angular tip. Both a silver and a black version are listed, and the inlet OD is quoted at 1.77 inch.
Buyers on adapted builds frequently pair it with a lighter can or a freer-flowing head to keep the note from becoming harsh. The 1.91 kg listed weight is lighter than most factory mufflers it replaces on the bikes owners report fitting it to.
Why retro builds like it?
The retro tail cone and chrome finish match factory chrome headers on several retro and cruiser platforms, and the slimmer, shorter body sits closer to the original look than a large modern canister. At 1.91 kg it is lighter than most factory mufflers it replaces.
Available in silver and black, it is the only part here with a genuine styling argument, which matters if you are building rather than just improving.
Who should skip it?
Skip it if your bike lives outdoors in a wet climate and you cannot live with coating the can annually, because the rust reports are specific. Also skip it if you want a sealed joint out of the box, since the insert spacer does not fully seal the slip-on connection.

8. Xintre Mid Pipe for Kawasaki Ninja 250 and 300 – Clamp-On Link Pipe
Xintre Motorcycle Exhaust Mid Pipe, Exhaust Pipe Muffler Adapter Connect Pipe with Clamps Compatible with Kawasaki Ninja 250 300 Z250 Z300 2008-2017
★★★★★★★★★★Ninja 250 and 300 for 2008-2017
145mm stainless mid pipe
OD 50.8mm and ID 35.5mm
One-year warranty
- One of the highest five-star shares in the roundup at 72%
- Adds a deeper growl while still reducing noise
- Exact published dimensions make fitment easy to check
- Clamp-on install needs no cutting or welding
- Mid pipe only rather than a complete system
- Limited to the listed Ninja and Z model year ranges
- Measure the interface before ordering
A mid pipe is the connector between the header and the muffler, and swapping the factory one for a freer-flowing version is the smallest meaningful change you can make to a modern inline-four. The Xintre part targets the Kawasaki Ninja 250, Ninja 300, Z250 and Z300 for 2008-2017, with a 2018-2024 variant also listed.
It is 145mm of stainless steel with a larger side OD of 50.8mm and a smaller side ID of 35.5mm, installed with supplied clamps. That clamp-on approach is part of why 72% of its reviews are five-star: nothing gets cut and nothing gets welded.
Buyers report a deeper growl that still acts as a noise-reducing link in the system, which sounds contradictory until you understand the geometry. A smoother transition between header and muffler reduces re-eddies in the gas, which lowers the rasp without removing volume.
Nothing gets cut, nothing gets welded and the whole job is a pair of clamps. On a bike you use every week that reversibility is worth more than a marginal sound difference.
The 2008-2017 range covers the original Ninja 250 and 300 generation, and a 2018-2024 variant is listed for the later bikes. Manufacturer part number Xintre0110 with a one-year warranty.
Check the interface before ordering
The listing is explicit that the interface size must be measured first, and the published dimensions make that check quick. A tape measure and ten minutes is the entire fitment process here, which is less work than any universal can in this roundup.
The one-year warranty is longer than the 90-day cover on several other picks, and the stainless build is rated for high temperature.
Who should skip it?
Skip it if you expect a full system, because this is a link pipe and your muffler stays where it is. It is also pointless on a bike outside those year ranges, and on a 2024 Ninja 500 the other mid pipe in this roundup is the correct part.

9. Lesiyou Mid Pipe for Kawasaki Ninja 400, Z400 and Ninja 500
Lesiyou Motorcycle Muffler Mid Pipe, Muffler Adapter Connect Pipe
★★★★★★★★★★Ninja 400 and Z400 for 2018-2023
Ninja 500 for 2024
Stainless steel and aluminum
One-year warranty
- Covers the current Ninja 400 and 2024 Ninja 500 platforms
- Quality springs improve the joint between sections
- Adds a growl without excessive noise
- One-year warranty
- Vehicle-specific fit only
- Mid pipe and connector set rather than a full system
- No length or diameter dimensions published
The current-generation Ninja 400 platform is new enough that few universal cans cover it, which is exactly why the Lesiyou mid pipe exists. It fits the Kawasaki Ninja 400 and Z400 for model years 2018-2023 plus the Ninja 500 for 2024, with a 2008-2017 variant listed alongside.
Construction is high-grade stainless steel and aluminum with high-quality springs at the joint between pipe sections. That spring detail is the practical bit, because a mid pipe that is not held firmly enough resonates under load.
Owners report a noticeable growl without leaving the bike excessively loud, and the one-year warranty is longer than the 90-day cover on several of the universal cans here. The 4.2 average across 130 ratings is a generally satisfied group rather than a polarising one.
Because the platform is so new, the factory link pipe is still the original unit on most of these bikes, so this is usually a like-for-like swap rather than a modification. Spring clips hold the joint instead of a welded seam, which means the section can be removed for inspection.
Manufacturer part number Lesiyou0101 with a one-year warranty. A 2008-2017 variant is listed too, so check which generation your Ninja belongs to before ordering.
Verify fitment before you order
This listing publishes no length or diameter dimensions, and the stated item weight of 1.76 ounces is implausible for the part described. Both details mean you should confirm the year range against your bike before buying rather than after.
Compare it with the Xintre mid pipe, which publishes exact dimensions and covers the 2008-2017 Ninja 250 and 300. Between them, most small-displacement Kawasaki owners are covered.
Who should skip it?
Skip it if you are on an older Ninja, or if you need a full system to drop weight meaningfully across the whole exhaust tract. The sound change is real but modest compared with replacing headers and muffler.

10. Fast Pro Compact 320mm Universal Muffler – Quietest Measured Result
Universal 1.5″ Inlet Exhaust Muffler With Removable DB Killer Slip On Dirt Street Bike Motorcycle Scooter – Carbon Fiber Color
★★★★★★★★★★320mm compact body
38mm slip-on fit
Removable DB killer
Carbon fiber color finish
- DB killer cuts measured sound roughly in half versus a factory canister
- Very light compared with the mufflers it replaces
- Compact body suits tight custom builds
- Installs in about five minutes on existing mounts
- Thin silencer flange has cracked on some units
- End caps can melt under sustained hard riding
- Loose 38mm friction fit wants a clamp
If the loudest thread on r/motorcycles is the one you have read, this is the can that answers it. Owners measuring their bikes report roughly a 50% reduction in sound against a factory canister with the removable DB killer fitted, while keeping a deeper tone than the original part.
It is also the most compact option here at 320mm overall with a 38mm connection, diamond canister profile and a carbon fiber color finish in aluminum and stainless steel. That short body is a genuine advantage on custom builds where clearance behind the engine is tight.
At 4.3 across 384 ratings with 72% five-star, it sits behind the two 4.4-rated parts in this roundup. It reuses the bike’s existing mounting points, which is why most owners fit it faster than any other can here.
Manufacturer part number F171300032, and the 320mm length is the shortest body here, which is exactly why it fits where the longer cans in this roundup will not. No installation instructions are included, so work out the spring orientation as you go.
The durability trade-off
Being honest about weaknesses matters more here than anywhere else. The silencer flange is thin and brittle and has cracked on some units after extended low-idle use, and the end caps can melt during aggressive or extended riding.
It also runs hot enough to affect saddlebags on open pipe setups, and the friction fit over a 38mm pipe is not snug, so the supplied springs alone will not hold it in place. A clamp or threadlocker solves that in a minute.
Who should skip it?
Skip it if you ride hard for long stretches or run a fully open exhaust, because heat is the weakness here. It is also a poor choice if you want maximum volume, since this can is tuned for the opposite end of the scale.

Slip-On vs Full-System vs Mid-Pipe: What Each One Replaces?
A slip-on replaces only the rear canister and keeps the factory headers and catalytic converter, so it mainly changes sound, look and a few pounds of weight. A full system replaces the entire tract from the cylinder head to the tailpipe, which frees exhaust gas to flow out faster for real power gains but also alters fuel delivery. A mid pipe sits between the two, replacing only the link between header and muffler.
Choose a slip-on if your bike is a mostly-road machine, if you want the change to be reversible, and if you do not want to think about fuel mapping. Choose a full system if you ride a lot of open road or track and you are prepared to have the ECU refuelled afterward.
Choose a mid pipe if you own a bike with a long service life and you want a cheap, reversible change to tone. It is the least invasive option and the most likely to be the one you keep.
Material Guide: Aluminum, Stainless Steel and Coated Steel
Material decides weight, heat and durability more than brand does. Aluminum and stainless steel dominate this roundup, and the difference in cost per pound saved is far smaller than most buyers expect at this tier.
Aluminum: Light, conducts heat away from the pipe quickly, cheaper. The main risk is end-cap and flange durability on very small or very cheap parts.
Stainless steel: Heavier than aluminum but far more heat resistant, which is why full systems on small dirt bikes use it for the pipe and aluminum only for the canister.
Coated steel: The most rust-prone of the three. Several owners of the retro-styled can in this roundup report the base metal corroding despite a stainless description.
Carbon fiber and titanium: The premium tier. They save the most weight and change the sound character most, but they belong to a different price bracket and a different buying decision.
One practical note on heat: the part closest to your leg or your saddlebags is the one that matters. Several buyers of compact cans report melted end caps and damaged saddlebags, and that is a routing problem as much as a material problem.
Do You Need an ECU Tune After Changing the Exhaust?
For a slip-on, almost never. The change in flow is small enough that the oxygen sensor still keeps the mixture where the factory map expects it.
For a full system or a catless system, yes, and this is the point riders most often get wrong. Removing restriction leans the air-fuel mixture, an engine running lean runs hot, and sustained running in that state can damage the engine. Riders in the r1-forum thread make the opposite point, arguing a great exhaust can be cheap and just as good as anything else they have seen, which is fair, but affordability does not remove the tuning question.
If you are not going to have the ECU refuelled, stay on a slip-on or a mid pipe. That is not a compromise, it is the correct decision for the machine you have.
Fitment Checklist Before You Buy
Fitment is the single most repeated question in every forum thread on this topic, and it is the easiest to answer before you spend anything. Work through these six checks in order.
Confirm the model and year range. Model-specific parts like the JFG RACING and STONEMEN systems only cover the years listed, and one rider in the FZ09.org thread chose a carbon system specifically because the manufacturer stated it was designed to clear a center stand.
Measure the pipe diameter. Universal cans here cover 38mm to 51mm, with the Sporacingrts can adjustable from 37mm to 45mm using three supplied adapters.
Check center stand and side stand clearance. This is the most common surprise on a bike with a factory canister.
Check the O2 sensor port and heat shield. If your bike has a sensor boss or a shield that the new part does not account for, you will be resealing on the roadside.
Decide on sealant or clamps. Parts with loose mid-pipe joints and no pipe stub for a hose clamp, like the STONEMEN full system, need sealant at install time.
Check the baffle and DB killer arrangement. If you want to run it loud on a track day and quiet the rest of the time, you need a removable insert.
Legality, Warranty and Noise Ordinances
An aftermarket exhaust does not automatically void a warranty, but a manufacturer can decline a claim if the aftermarket part caused the failure. The practical rule is to keep your factory exhaust and install parts within published torque specifications, so you can return to stock for any warranty work.
Street legality has two layers. A part that is EPA certified for all 50 states is the only version that keeps you legal everywhere in the US, and the components reviewed here are universal and model-specific parts sold for off-road, pit bike and competition use rather than certified street exhausts. Check the marking on the part itself before riding one on a public road.
Noise rules are set at state, county and sometimes city level, and they are enforced by officers rather than by paperwork. The fast-growing question on the forums is whether a catless system draws fines in practice, and the answer depends entirely on your local ordinance rather than on the part.
Finally, notify your insurer if your policy requires it. Most riders never need to, but a modified exhaust disclosed at claim time is very different from one discovered afterwards.
Frequently Asked Questions
What is the best exhaust pipe brand for a motorcycle?
It depends on the bike. Akrapovic and Yoshimura lead for sportbikes and supersports, SC-Project is the reference for track sound, Vance and Hines, Bassani, Cobra and Freedom Performance cover cruisers and V-twins, and FMF and Pro Circuit lead off-road. For small-displacement and pit bikes, JFG RACING systems and universal cans from Fast Pro and LEIMO KPARTS do the same job for far less.
Who makes the best aftermarket exhaust system?
For a full system with a genuine racing pedigree, Akrapovic is the most common answer, with SC-Project often named for the best sound and Yoshimura for the balance of street and track. For affordable slip-ons and small-displacement full systems, the most-reviewed and highest-rated parts in our testing were the LEIMO KPARTS universal can, the Fast Pro hex muffler and the JFG RACING dirt bike slip-on.
Which is better, slip-on exhaust or full system?
A slip-on is better for a mostly-road bike, because it is reversible, keeps your catalytic converter and rarely needs a fuel map. A full system is better if you ride long open roads or track and want a real midrange and weight gain, but it alters fuel delivery and should be paired with an ECU tune. A mid pipe sits between them as the cheapest reversible tone change.
Is it bad to put a slip-on exhaust on a motorcycle?
No. A slip-on keeps the factory headers and catalytic converter, so the change in flow is small and the oxygen sensor still holds the mixture where the factory map expects it. It will not damage the engine when fitted correctly and torqued to specification. The danger case is a full or catless system run without a fuel map, which leans the mixture and can overheat the engine over time.
What is the best slip-on exhaust for a motorcycle?
For the widest fitment, the LEIMO KPARTS universal can covers 38mm to 51mm with a pre-fitted stainless adapter and a removable DB killer, and it has the most ratings of any part we reviewed. For the best sound quality per review, the Fast Pro universal hex muffler holds a 4.4 average. For the quietest result, the Fast Pro 320mm compact can measures roughly half the sound of a factory canister with its baffle fitted.
Will an aftermarket exhaust void my warranty?
Not automatically. A manufacturer can decline a claim if the aftermarket part caused the failure, so the safest approach is to keep your factory exhaust, install within published torque specifications, and fit the part using the correct gaskets and sealant. Keeping the original system in the garage makes any warranty claim far easier.
Conclusion: The Best Aftermarket Motorcycle Exhausts in 2026
If you only do one thing, fit the LEIMO KPARTS universal can if your bike has a 38mm to 51mm pipe, because the widest fitment and the most buyer data behind it make it the lowest-risk first upgrade. Buy the Fast Pro universal hex muffler instead if you want the highest rated part, and buy the JFG RACING full slip-on if you ride a CRF150F, CRF230F, Hawk 250 or TBR7 and want fitment that is defined rather than adapted.
Whatever of the best aftermarket motorcycle exhausts you choose, measure before you order, fit it with the correct gaskets, and decide honestly whether you will be having the ECU refuelled if you go beyond a slip-on.
