A strong dirt bike muffler choice matches your engine and exhaust inlet while giving you the right combination of fitment, construction, and included installation parts. The SHIQINHA 1.1-Inch Exhaust Kit is our Best Overall pick for riders with compatible small-engine bikes: it lists broad engine fitment and includes a heat shield, clamps, and metal cable ties. But there is no universal size that fits every dirt bike.
These products range from a 39mm inlet for 47–50cc two-strokes to 28mm options for pit bikes and 38–51mm slip-ons for larger or varied motorcycle setups. Check your existing pipe and mounting arrangement before ordering, and treat brand-model compatibility claims as a starting point to verify against your bike.
The SHIQINHA 1.1-Inch Exhaust Kit leads because it lists fitment for 110cc and 125cc four-stroke engines, smaller two-strokes, and a wide range of small-engine applications. It also includes a heat shield, three muffler clamps, and four metal cable ties, making it the most complete listed package. Its 1.1-inch connection still needs to match your bike’s exhaust dimensions, so verify the fit before purchase rather than relying on engine size alone.

Detailed Reviews: Best Muffler For Dirt Bike

#1 · Best Overall
1. SHIQINHA 1.1-Inch Exhaust Kit
- Weight: 0.72 kg
- Compatible with Vehicle Type: ATV, Go Kart, Golf Cart, Lawn Mower, Motorcycle
Best for: Small-engine kit versatility.
Why it ranks #1: Lists fitment for 110cc and 125cc four-strokes plus many small engines, and includes a heat shield, three clamps, and four metal cable ties.
A broad engine-compatibility list is the SHIQINHA kit’s defining feature, spanning 50cc–125cc bike engines and several named small-engine families. That range makes it relevant beyond pit bikes, including mini bikes, ATVs, go-karts, lawn mowers and generators. Its included heat shield, clamps and metal ties give the exhaust replacement a more complete parts package.
The stated 1.1-inch fit and compatibility with 110cc and 125cc four-stroke engines, 47cc–50cc two-strokes, and named Predator and Honda GX engines help buyers evaluate a range of small-machine applications. The package includes a heat shield, three exhaust clamps and four metal cable ties alongside the silencer, so more of the listed installation components arrive together. Its vehicle list also extends to go-karts, lawn mowers and generators, not just dirt bikes.
- Compatibility lists multiple small-engine families and capacities
- Includes exhaust heat shield
- Includes three muffler exhaust clamps
- Includes four metal cable ties
- The listing identifies a 1.1-inch fit, limiting use with other connection sizes.
Skip it if you need a 28 mm muffler with a specifically listed dirt-bike fit; GREHUA names many 50cc–125cc pit-bike models and uses 28 mm connections.
Pick SHIQINHA when a wide range of listed small-engine applications and bundled clamps matter more than a bike-only part. Check that the 1.1-inch connection suits the intended exhaust before choosing this kit.

#2 · Broad Pit-Bike Fit
2. GREHUA 28mm Exhaust Muffler
- Weight: 1.52 kg
- Material: Metal
- Compatible with Vehicle Type: Motorcycle
- Inlet Connection Size: 28 millimeters
Best for: 28 mm pit-bike coverage.
Why it ranks #2: Its 28mm inlet is listed for 50cc–125cc bikes and numerous named pit-bike brands; the package also comes with heat wrap.
Compatibility with a long list of 50cc–125cc pit bikes makes the GREHUA muffler a broadly targeted choice within that class. It includes heat wrap and uses 28 mm inlet and outlet connections. The listing also flags an important model exception: it does not fit the Apollo RFZ 125.
The 28 mm inlet and outlet create a clearly specified connection size, while the application list covers numerous named Chinese-brand pit bikes and 50cc through 125cc exhausts. A heat wrap is included with the exhaust, giving buyers an added component alongside the metal muffler. Because the listing explicitly excludes the Apollo RFZ 125 and limits certain Honda compatibility, those exceptions matter when narrowing fit; the extensive model list should not be read as universal compatibility.
- 28 mm inlet and outlet connections
- Heat wrap included
- Listed for many 50cc–125cc pit bikes
- Names numerous Chinese-brand models
- Not compatible with the Apollo RFZ 125, per the fitment listing.
Skip it if you own an Apollo RFZ 125; the listing explicitly excludes it, while the 28 mm ABCERRSI option is described for universal dirt-bike and ATV fitment.
Choose GREHUA if your pit bike appears in its extensive model list and uses 28 mm connections. The included heat wrap adds to the package, but the Apollo RFZ 125 exclusion and Honda caveat require attention.

3. EOPOAYI 28mm Muffler
- Weight: 0.76 kg
- Material: Metal
- Compatible with Vehicle Type: ATV, Motorcycle
- Inlet Connection Size: 1 1/8" in
Best for: Broad small-engine fit list.
Why it ranks #3: A 28mm-style muffler listed for 110cc and 125cc engines and many small-engine applications, with a stated six-month warranty.
Compatibility spanning pit bikes, ATVs, go-karts, lawn mowers and generators makes this EOPOAYI muffler unusually broad in its stated small-engine applications. Its title focuses on 125cc and 110cc dirt bikes, while the feature list adds multiple engine families and a 1 1/8-inch inlet for connection checks.
The feature list names 110cc and 125cc four-stroke engines, several Predator and GX families, and other small OHV engines, extending use beyond dirt bikes to ATVs, go-karts, lawn mowers and generators. That broad list can help buyers assess different machines, but the 1 1/8-inch inlet remains the key connection measurement. The metal muffler is listed at 0.76 kg, and the included component is the exhaust muffler rather than a stated multi-part installation kit.
- Lists 110cc and 125cc four-stroke applications
- Compatibility includes several named small-engine families
- 1 1/8-inch inlet connection specified
- Metal muffler weighs 0.76 kg
- Only the exhaust muffler is listed as included; no extra installation hardware is specified.
Skip it if you need a kit that includes a heat shield, clamps and cable ties; SHIQINHA includes those parts with its exhaust silencer.
This EOPOAYI is suited to buyers whose dirt bike or small machine appears in its compatibility list and has a matching 1 1/8-inch inlet. Its listed package is a single muffler, not a hardware bundle.

#4 · Adapter-Ready
4. ABCERRSI 28mm Slip-On
- Weight: 1.2 lb
- Material: Aluminum
- Compatible with Vehicle Type: ATV, Motorcycle, Scooter
Best for: Low-midrange response focus.
Why it ranks #4: The 28mm aluminum muffler includes an adapter ring supporting 26mm and 30mm original interfaces, useful when the stock connection differs.
A porous baffle paired with a spiral airflow channel is the ABCERRSI muffler’s clearest differentiator, with the listing connecting that structure to low- and mid-speed torque. The 28 mm outlet and adapter ring for 26 mm or 30 mm interfaces also give buyers more connection options than a single-size outlet alone.
The built-in porous baffle and spiral airflow channel are stated to optimize torque output between 3000 and 6000 rpm, with a claimed 12% low-torque increase over straight-through types. These claims make the internal design relevant to riders focused on lower-speed response. Its adapter ring supports 26 mm and 30 mm original interfaces, while the listed 28 mm outlet and aluminum construction help buyers assess connection and material needs for dirt bikes, street bikes, scooters or ATVs.
- Porous baffle and spiral airflow channel
- Listed 3000–6000 rpm torque focus
- Adapter ring supports 26 mm and 30 mm interfaces
- Aluminum construction
- The listed torque gain is a manufacturer claim, not a separately documented measurement.
Skip it if you need a complete kit with a heat shield and multiple clamps; SHIQINHA includes those components with its small-engine exhaust.
Consider this ABCERRSI when its adapter-ring sizes match your original interface and lower-to-midrange response is a priority. Its torque figures are stated product claims, so treat them as guidance rather than independent performance verification.

5. Sporacingrts Black Muffler
- Weight: 0.65 kg
- Material: Alloy Steel, Aluminum
- Compatible with Vehicle Type: Atv,Bike,Dirt Bike
- Inlet Connection Size: 28 millimeters
Best for: Direct-replacement compact fit.
Why it ranks #5: Lists compatibility with 50cc, 110cc, and 125cc dirt and pit bikes, with a 28mm inlet and a stated 244mm length.
Its 26 mm mounting-hole distance gives the Sporacingrts muffler a concrete fit dimension for buyers replacing a matching unit. The listing also supplies a 244 mm length and 28 mm inlet, while aluminum-and-steel construction and multi-angle installation support practical replacement planning for specified Chinese 50cc, 110cc and 125cc vehicles.
The 26 mm mounting-hole distance, 244 mm length and 28 mm inlet provide useful measurements for comparing the part with an existing exhaust before installation. Sporacingrts describes the size as fully adapted for direct replacement and says installation is simple without instructions. Aluminum and alloy steel are listed materials, while supported applications include QUAD ATVs, dune buggies and Chinese dirt or pit bikes in 50cc, 110cc and 125cc classes.
- 26 mm mounting-hole distance specified
- 28 mm inlet connection
- Aluminum and alloy-steel construction
- Multi-angle installation is listed
- The stated 28 mm inlet and 26 mm mounting-hole spacing limit its fit to matching layouts.
Skip it if you need a muffler explicitly listed for 47cc–50cc two-stroke mini bikes; YLQYYH specifies that application and 39 mm bolt spacing.
This Sporacingrts replacement suits owners of compatible Chinese pit bikes, ATVs or dune buggies who can use its specified dimensions. The 28 mm inlet and 26 mm hole spacing make matching the existing layout essential.

#6 · Two-Stroke Fit
6. YLQYYH 49cc Muffler
- Compatible with Vehicle Type: Motorcycle
- Inlet Connection Size: 1.53 in
Best for: 47cc–50cc mini-bike replacement.
Why it ranks #6: Targets 47cc, 49cc, and 50cc two-stroke mini dirt bikes, with a stated 1.53-inch bolt spacing to check against the original.
A stated 39 mm bolt spacing identifies the YLQYYH muffler for buyers matching a compact mini dirt bike exhaust layout. The listing targets 50cc mini dirt bikes and names 47cc, 49cc and 50cc two-stroke applications in its title, keeping the use case focused rather than broadly universal.
The product is specifically described for a 50cc mini dirt bike, with the title extending the stated application to 47cc and 49cc two-stroke off-road and pit bikes. Its 39 mm bolt spacing, also given as 1.53 inches, is a useful measurement to compare with the mounting points on the current exhaust. The listed connection dimensions help narrow the fit check, but the available product details do not identify a broader vehicle range or bundled installation parts.
- Targets 50cc mini dirt bikes
- Title names 47cc, 49cc and 50cc two-stroke bikes
- 39 mm bolt spacing specified
- 1.53-inch inlet connection listed
- Its stated application is limited to 50cc mini dirt bikes.
Skip it if you need listed compatibility across 70cc–125cc pit bikes; GREHUA names those capacities and specifies a 28 mm exhaust.
This YLQYYH replacement is for riders with a 47cc–50cc mini dirt bike and matching 39 mm mounting spacing. Its narrow stated application makes it a poor choice for buyers seeking a broader pit-bike fit range.

View on AmazonWhy it ranks #7: Lists a 28mm aperture and a 22–32mm buckle range for dirt bikes and ATVs, plus an adapter ring for 26mm and 30mm interfaces.
A built-in porous baffle and spiral airflow channel define this ABCERRSI muffler, with the listing linking them to torque at 3000–6000 rpm. Its adapter ring supports 26 mm and 30 mm original interfaces, while a 28 mm aperture and stated buckle range provide additional dimensions for fit planning.
The porous baffle and spiral airflow channel are described as optimizing torque between 3000 and 6000 rpm, with a stated 12% low-torque gain over a straight-through type. Its adapter ring accommodates 26 mm or 30 mm original interfaces, while the 28 mm aperture and 22–32 mm buckle range add measurements to compare with the exhaust setup. Aluminum construction and a 260 mm product length give buyers further material and space information for installation planning.
- Porous baffle and spiral airflow channel
- Listed 3000–6000 rpm torque focus
- Adapter ring supports 26 mm and 30 mm interfaces
- 22–32 mm buckle range specified
- The stated torque increase is a product claim, not an independently documented measurement.
Skip it if you need a muffler for 38–51 mm pipes; LEIMO KPARTS lists that larger diameter range and a removable DB killer.
Choose this ABCERRSI if your connection matches its adapter options and you value its listed lower-speed torque focus. Its dimensions and torque statements are specific product claims, so check the actual installation layout before selecting it.

8. EOPOAYI 1.1-Inch Muffler
- Weight: 0.68 kg
- Material: Metal
- Compatible with Vehicle Type: ATV, Motorcycle
- Inlet Connection Size: 1.1 in
Best for: Compact-engine 1.1-inch option.
Why it ranks #8: A simple 1.1-inch inlet option specifically titled for 110cc and 125cc pit dirt bikes, but the listing provides fewer fitment details.
A 1.1-inch inlet sets the EOPOAYI slip-on apart for riders shopping around that specific connection size. Its title names 125cc and 110cc pit dirt bikes, while the metal muffler is listed for ATV and motorcycle use. The available specifications are spare, so this is a size-led choice rather than a feature-rich kit.
The 1.1-inch inlet gives buyers a concrete connection measurement to compare with their existing exhaust, and the title identifies 110cc and 125cc pit dirt bikes as target applications. Its metal construction supplies the listed material detail, while the 0.68 kg weight makes the unit’s mass clear for replacement planning. The product information lists an exhaust muffler as the included component, so buyers should not expect additional installation hardware based on the supplied details.
- 1.1-inch inlet connection size
- Title identifies 110cc and 125cc pit dirt bikes
- Metal construction
- 0.68 kg listed item weight
- The listed package includes only an exhaust muffler, with no additional hardware specified.
Skip it if you want a listed heat shield, clamps or multiple adapters; SHIQINHA’s kit includes a heat shield and three exhaust clamps.
This EOPOAYI suits a buyer seeking a basic metal slip-on for a stated 110cc or 125cc pit dirt bike and a 1.1-inch inlet. Its sparse component listing makes it less suited to shoppers seeking a bundled hardware kit.

9. LEIMO KPARTS Carbon Slip-On
- Weight: 1.37 kg
- Material: Aluminum, Stainless Steel
- Compatible with Vehicle Type: Bike,Motorcycle,Dirt Bike,Scooter,Atv,Scooters
- Inlet Connection Size: 1.5 in
Best for: Broad-diameter universal upgrade.
Why it ranks #9: Its universal 38–51mm fitment includes dirt bikes and it has a removable DB killer, but the large inlet range needs careful measurement.
A 38–51 mm universal fit is the LEIMO KPARTS muffler’s key advantage, covering a stated range of dirt bikes, street bikes, scooters, ATVs and quads. Its removable DB killer also lets riders change the sound effect, while the carbon-fiber-style finish and aluminum-and-stainless-steel construction distinguish it from a plain replacement silencer.
The 38–51 mm fit range gives this slip-on flexibility across several listed vehicle types, but the exhaust pipe must fall within that diameter range. A removable DB killer provides a way to choose between sound effects without replacing the muffler. Aluminum and stainless steel form the body, and the listing describes it as corrosion- and rust-resistant. At 1.37 kg, it is also specified as a lighter-weight option for riders considering overall exhaust weight.
- Fits stated 38–51 mm muffler diameters
- Removable DB killer changes sound effect
- Aluminum and stainless-steel construction
- Listed for dirt bikes, scooters, ATVs and quads
- The 38–51 mm range does not cover pipes outside those diameters.
Skip it if you need a muffler for a pipe narrower than 38 mm; the 28 mm Sporacingrts unit is the more relevant listed size.
Choose this LEIMO KPARTS slip-on if your bike’s exhaust measures within 38–51 mm and you want a removable DB killer. Its broad vehicle listing is useful, but the diameter range is the key fit boundary.

10. PACEWALKER Blue Slip-On
- Weight: 1.5 kg
- Material: Stainless Steel, Titanium
- Compatible with Vehicle Type: Motorcycle
- Inlet Connection Size: 38-51 millimeters
Best for: Blue-finish universal slip-on.
Why it ranks #10: The titanium-alloy slip-on lists a 38–51mm inlet and removable DB killer, but its compatibility details emphasize motorcycles and scooters rather than dirt bikes.
A double-head blue baking finish gives the PACEWALKER slip-on its most visible distinction, with the listing describing a gradient appearance and rust resistance. Its 38–51 mm inlet range and removable DB killer add fit and sound-effect considerations, making it relevant to motorcycle and scooter owners seeking a wide-diameter option.
The 38–51 mm inlet range accommodates a broad set of stated motorcycle and scooter pipe diameters, so the measured connection remains the main fit consideration. A removable DB killer lets the rider change the sound effect, while the titanium-alloy body and stainless-steel connector specify the material combination. The blue baking process is described as adding strength and rust resistance as well as its gradient finish, combining a visual feature with a stated durability benefit.
- 38–51 mm inlet range
- Removable DB killer changes sound effect
- Titanium-alloy body with stainless-steel connector
- Blue baking finish is described as rust-resistant
- The 38–51 mm inlet range does not suit smaller connection diameters.
Skip it if you need a 28 mm pit-bike muffler; GREHUA lists 28 mm connections and many 50cc–125cc dirt-bike models.
PACEWALKER fits riders seeking a blue-finished universal slip-on with a removable DB killer. It suits listed motorcycles and scooters only when their connection measures within 38–51 mm, so smaller pit-bike outlets are outside its stated range.

View on AmazonWhy a stated fit may still not fit your bike
A muffler can be listed for your engine size and still fail to match your exhaust connection or mounting points. The listings show why: the YLQYYH 49cc Muffler specifies 1.53-inch bolt spacing, while several pit-bike options use a 28mm connection and the LEIMO KPARTS Carbon Slip-On and PACEWALKER Blue Slip-On cover 38–51mm inlets. Those are not interchangeable dimensions.
Measure the outside diameter of the pipe where the muffler joins, and compare it with the product’s stated inlet or adapter range. Also check bolt spacing, clearance, and how the muffler attaches; the Sporacingrts Black Muffler lists a 26mm mounting-hole distance.
A broad compatibility list is useful for narrowing choices, not proof that every model year or exhaust configuration fits. If the listing does not give a dimension you need, confirm it with the seller before ordering.
Muffler changes can affect sound and setup
A replacement muffler can change exhaust sound, and the listings provide no sound measurements or assurance that a particular option meets local noise rules. The GREHUA 28mm Exhaust Muffler listing says it makes the cycling sound louder; the LEIMO KPARTS Carbon Slip-On and PACEWALKER Blue Slip-On have removable DB killers, which allow different sound effects but do not establish a decibel level. Fit is only part of the decision: riders should consider where they ride and check applicable noise requirements before changing the exhaust.
These listings also do not establish whether a muffler requires jetting or fuel adjustments. After installation, follow the bike maker’s guidance and look for exhaust leaks or changes in running behavior.
A slip-on label alone does not confirm that a part will work correctly with every engine or existing exhaust system.
How to Choose a Dirt Bike Muffler
Match inlet and mounting dimensions
Choose by the measured exhaust connection and mounting points, not by engine size alone. The pit-bike options include 28mm connections, while the LEIMO KPARTS Carbon Slip-On and PACEWALKER Blue Slip-On list 38–51mm inlets. The YLQYYH 49cc Muffler states 1.53-inch bolt spacing, and the Sporacingrts Black Muffler lists 26mm mounting-hole distance.
The ABCERRSI 28mm Slip-On says its adapter ring supports 26mm and 30mm original interfaces. Riders replacing a small pit-bike muffler should start with the 28mm group; owners with a larger pipe should measure before considering a 38–51mm universal slip-on.
Confirm the mounting arrangement separately because a matching inlet does not guarantee matching bolt locations.
Check engine and model compatibility
Look for the closest match to your bike’s engine, model, and exhaust configuration. The SHIQINHA 1.1-Inch Exhaust Kit lists 110cc and 125cc four-strokes as well as 47cc–50cc two-strokes and many small engines. The GREHUA 28mm Exhaust Muffler lists 50cc–125cc fitment and many named pit-bike brands, while the YLQYYH 49cc Muffler is specifically for 47cc, 49cc, and 50cc two-strokes.
The universal LEIMO KPARTS Carbon Slip-On instead covers 38–51mm pipes. A rider with a named pit-bike model should favor a listing that names it; a rider with an unusual setup may consider a universal option only after checking its dimensions and mounting needs.
Consider materials and included parts
Compare construction and package contents when two mufflers otherwise appear compatible. The SHIQINHA 1.1-Inch Exhaust Kit includes a heat shield, three exhaust clamps, and four metal cable ties, while the GREHUA 28mm Exhaust Muffler comes with heat wrap. The LEIMO KPARTS Carbon Slip-On combines aluminum and stainless steel, and the PACEWALKER Blue Slip-On lists titanium alloy with a stainless-steel connector.
The Sporacingrts Black Muffler uses alloy steel and aluminum. Riders who need several fitting pieces should look first at the SHIQINHA kit; those seeking a particular material combination may prefer one of the universal slip-ons, provided the inlet matches.
Do not assume included clamps or heat protection replace checking fit or installation requirements.
Which Dirt Bike Muffler Should You Choose?
For a compatible small-engine bike and a package with several installation parts, choose the SHIQINHA 1.1-Inch Exhaust Kit; it has the broadest listed engine fitment and includes a heat shield, clamps, and cable ties. Riders with a named pit-bike model in the 50cc–125cc range should compare the GREHUA 28mm Exhaust Muffler’s compatibility list and included heat wrap. If your original connection is 26mm or 30mm, the ABCERRSI 28mm Slip-On specifically lists an adapter ring for those interfaces.
For a 47cc–50cc two-stroke mini bike, consider the YLQYYH 49cc Muffler after checking its bolt spacing. Choose a 38–51mm universal slip-on only if your measured pipe falls in range.
Verify dimensions and local noise rules before ordering.

Frequently Asked Questions
How do I measure my dirt bike’s exhaust inlet and pipe before ordering a muffler?
Measure the outside diameter of the bike’s exhaust pipe where the muffler connects, and compare it with the muffler’s listed inlet size. Also check the available pipe length and mounting or bolt spacing if applicable. Confirm whether an adapter is included; listed engine size alone does not guarantee a match.
Will replacing a dirt bike muffler require carburetor or fuel-injection adjustments?
Not necessarily; whether adjustment is needed depends on the bike and the exhaust change. After installation, follow the manufacturer’s guidance and watch for changes in running, such as poor response or unusual operation. If the bike runs differently, consult a qualified mechanic rather than assuming the new muffler is correctly tuned.
How can I check whether a louder aftermarket muffler is legal where I ride?
Check the noise and equipment rules that apply where you ride, including local trail, land-manager, and road-use requirements if relevant. Do not assume a muffler is legal because it fits the bike or is sold as an aftermarket part. If the rules are unclear, ask the relevant authority before installing or riding.
When should I choose a muffler with an adapter ring?
Choose one when your measured exhaust connection is 26mm or 30mm and the muffler listing specifically confirms an adapter ring for that interface. The ABCERRSI 28mm slip-on lists this option. Measure your pipe first and check the included parts, since a stated 28mm inlet alone does not establish compatibility.
What should I check before ordering a muffler for a 47cc–50cc two-stroke mini bike?
Confirm that the listing is intended for a 47cc–50cc two-stroke mini bike, then compare the mounting bolt spacing and exhaust connection with your bike. The YLQYYH 49cc muffler is one option identified for this category, but check those dimensions before ordering rather than relying on engine size alone.
Final Words
For a compatible small-engine bike, the SHIQINHA 1.1-inch kit is the most complete listed package, with broad stated engine fitment, a heat shield, clamps, and cable ties. Match its connection to your measured exhaust before ordering. For named pit-bike fitment, compare GREHUA; for a 26mm or 30mm interface, consider ABCERRSI’s adapter ring.
Check bolt spacing on the mini-bike option, and verify local noise rules.
