Best Exhaust System For Motorcycle: Full Systems and Slip-Ons

#1 · Best Overall

1. III BLACK3 2-into-1 System

Best for: Long-distance Harley touring.

Why it ranks #1: A complete 2-into-1 system is listed for Harley-Davidson Touring models from 2009–2025 and uses 304 stainless steel throughout.

Equal-length front and rear pipes give this 2-into-1 system its defining feature, aimed at smoother exhaust flow and balanced exhaust pulses. That layout is intended to support more stable performance output and reduce vibration, making it a particularly relevant option for riders covering long distances on compatible Harley-Davidson Touring motorcycles.

The complete 2-into-1 system is specified for Harley-Davidson Touring models from 2009 through 2025, including Street Glide, Road Glide, Road King and Electra Glide variants named in the listing. Its equal-length front and rear pipes are linked to smoother flow and balanced pulses, with reduced vibration cited as a touring comfort benefit. The full system uses 304 stainless steel for both headers and muffler body, giving buyers one stated material across the assembly rather than a collection of separately specified materials.

Skip it if you ride a scooter or need a universal small slip-on; PACEWALKER's 1.5–2-inch muffler covers a broader range of pipe diameters.

Harley-Davidson Touring owners seeking a complete 2-into-1 system for longer rides should consider this equal-length, 304 stainless option. Its stated application is specific to Touring models from 2009–2025, so check that your motorcycle is among the listed families.

#2 · Best Vulcan Fit

2. SHARKROAD Vulcan Pipes

• Material Type: Alloy Steel
• Compatible with Vehicle Type: Motorcycle
• Weight: 11.93 kg

Best for: Vulcan 1700 touring owners.

Why it ranks #2: These slip-on pipes are specifically listed for Kawasaki Vulcan Vaquero 1700 and Voyager 1700 touring models, with hardware included.

Specific application to Kawasaki Vulcan Vaquero 1700 and Vulcan Voyager 1700 touring models is the clearest reason to consider these SHARKROAD slip-on pipes. The listing identifies alloy steel construction and included hardware, making this a model-focused option rather than a broadly specified universal muffler.

The named Vaquero 1700 and Voyager 1700 applications narrow the intended buyer to owners of those Kawasaki touring models, rather than riders choosing by a universal pipe-diameter range. SHARKROAD identifies the product as slip-on pipes and lists alloy steel as the material. Hardware is included, which gives the package an installation component, though the supplied details do not describe the hardware contents or provide pipe dimensions. Confirming the exact model application is therefore central to evaluating this system.

Skip it if you ride a GY6 125/150cc scooter; EPJHKBE's GY6 stainless system names that engine family instead.

This SHARKROAD option suits owners of the specifically named Kawasaki Vulcan 1700 touring models who want slip-on pipes with hardware included. Its application is narrow, and the supplied details do not give pipe dimensions for broader compatibility checks.

#3 · Best GY6 System

3. EPJHKBE GY6 Exhaust

• Material Type: Stainless Steel
• Compatible with Vehicle Type: Motorcycle
• Weight: 1.7 lb

Best for: GY6 scooter replacement system.

Why it ranks #3: The stainless steel system targets GY6 125/150cc scooters and includes a copper gasket, bolts, nuts, and washers.

A built-in muffler canister gives this EPJHKBE exhaust its specified deep, low-frequency tone while managing noise for GY6 125/150cc scooters. Stainless-steel construction with TIG-welded joints is also stated, making this a targeted replacement option for riders seeking a system for that engine family.

The listed compatibility is for GY6 125/150cc scooters and GY6 replacements, so this is a more focused choice than universal slip-ons. A built-in silencer is described as producing a deep, low-frequency sound without an overly piercing or raspy tone. The stainless-steel body and TIG-welded joints are cited for durability and heat resistance. A copper gasket, two bolts, two nuts and two washers are included, providing specified installation hardware alongside the exhaust.

Skip it if you need a muffler for a 38–51mm range of motorcycle pipes; Fast Pro's F17130008 lists that universal diameter range.

This suits owners replacing or upgrading exhaust hardware on a GY6 125/150cc scooter who want a silenced, low-frequency tone and supplied fasteners. Its stated compatibility is specific to the GY6 family, not general motorcycle fitment.

#4 · Best Removable DB Killer

4. PACEWALKER Carbon Muffler

• Material Type: Aluminum, Stainless Steel
• Compatible with Vehicle Type: ATV, Dirt Bike, Motorcycle, Scooter

Best for: Adjustable-sound universal slip-on.

Why it ranks #4: This 365mm aluminum-and-stainless slip-on accepts 38–51mm pipes and includes a removable DB killer and mounting clamp.

A removable DB killer lets this PACEWALKER muffler offer different sound effects, giving riders a way to change its sound configuration. The 365mm aluminum-body silencer has a stainless-steel connector and is listed for 38–51mm exhaust pipes, spanning motorcycles, scooters, ATVs and dirt bikes.

Its 51mm connection and included 38–51mm adapter support use across the listed pipe-diameter range, while the mounting clamp is included for attaching the slip-on. The removable DB killer provides the stated sound adjustment; the product description characterizes the sound as deep and slightly throaty rather than terribly loud. At 365mm overall length, the muffler uses an aluminum body with a stainless-steel connector, so buyers can assess both its dimensions and material combination before installation.

Skip it if you need a compact 210mm silencer; the Generic 6965MXM-51 is listed at that shorter overall length.

Choose this for a street bike, scooter, ATV or dirt bike with a 38–51mm pipe when adjustable sound is useful. Its 365mm length and slip-on connection remain important physical fit considerations before you commit to installation.

#5 · Best Dual Outlet

5. PACEWALKER Dual-Outlet Muffler

• Material Type: Aluminum, Stainless Steel
• Compatible with Vehicle Type: Motorcycle, Scooter, Dirt Bike, ATV, Street Bike

Best for: Dual-outlet universal slip-on.

Why it ranks #5: Its dual-outlet slip-on design is listed for 38–51mm pipes and comes with an exhaust pipe, bracket, and spring.

A dual-outlet tailpipe gives this PACEWALKER slip-on a distinctive exhaust layout, with the listing associating the design with reduced overall weight and an outstanding sound. Its 368mm length and 38–51mm connection range help buyers assess both physical fit and pipe compatibility.

The 38–51mm connection range is listed for motorcycles, scooters, dirt bikes, ATVs and street bikes, so the existing pipe diameter remains the key fit consideration. At 368mm long, the muffler’s body dimensions can also be compared with available clearance. Its dual-outlet design is described as reducing overall weight, and the package includes an exhaust pipe, bracket and spring. Those included pieces give buyers named mounting components for the slip-on installation workflow.

Skip it if you need a 210mm compact silencer; the Generic 6965MXM-51 lists that shorter overall length.

Choose this for a motorcycle, scooter, dirt bike or ATV with a compatible 38–51mm pipe when a dual-outlet tailpipe suits your setup. Its 368mm length makes clearance a practical consideration before installation.

6. LEIMO KPARTS Carbon Muffler

• Material Type: Aluminum, Stainless Steel
• Compatible with Vehicle Type: Bike,Motorcycle,Dirt Bike,Scooter,Atv,Scooters
• Weight: 1.37 kg

Best for: Removable-baffle sound adjusters.

Why it ranks #6: This universal carbon-finish slip-on fits listed pipe diameters of 38–51mm and has a removable DB killer.

A removable DB killer is the defining practical feature of this LEIMO KPARTS muffler, allowing different sound effects from the same slip-on. Its 38–51mm universal fit is listed for dirt bikes, street bikes, scooters, ATVs and other bikes, with an aluminum-and-stainless construction and carbon-fiber finish.

The stated 38–51mm pipe range gives this muffler broad listed vehicle coverage, while its slip-on format makes the existing pipe diameter central to compatibility. Riders can remove the DB killer to change the sound effect, according to the supplied description. Aluminum and stainless steel form the construction, and the listing says the material is corrosion- and rust-resistant. These features make it useful to buyers comparing adaptable sound and multi-category fit, though the listing does not provide an overall length.

Skip it if you need a stated overall length before checking clearance; PACEWALKER's 365mm muffler provides that dimension.

Consider this universal slip-on if your bike or scooter has a 38–51mm pipe and changing the sound effect matters. The listing does not specify its overall length, so buyers with tight exhaust clearance should prioritize a model with dimensions.

#7

7. Generic Carbon Slip-On

• Material Type: Stainless Steel
• Compatible with Vehicle Type: Motorcycle
• Weight: 1.17 kg

Best for: Compact 51mm slip-on buyers.

Why it ranks #7: The 210mm slip-on has a 51mm connection and includes a spring puller and fixing rings, though its stated fitment is less specific.

At 210mm long, this carbon-fiber slip-on keeps its listed overall length compact while offering a 51mm connection. The muffler is described as reducing noise, and its included spring puller and fixing rings support mounting and removal without relying on an unspecified installation kit.

The 2.0-inch connection and slip-on format make pipe diameter the key compatibility check for this muffler; the listing names motorcycles including Z900, GSXR750 and CBR650 among its applications. A spring puller and fixing rings are included, giving buyers the stated hardware for mounting and later removal. Its carbon fiber, stainless steel and aluminum construction combines the named materials, while the 210mm overall length helps identify whether the compact body suits the available space on a particular bike.

Skip it if you need an adjustable 38–51mm connection; Fast Pro's F17130008 lists that range for its universal muffler.

This is a candidate for motorcycle owners whose pipe accepts a 51mm slip-on and who want a short muffler with included mounting pieces. Verify the listed connection against your setup; the product does not give the broader adapter range of some universal options.

#8

8. YZCHAIN Carbon Slip-On

• Compatible with Vehicle Type: Motorcycle
• Weight: 2.1 lb

Best for: Adjustable-adapter slip-on installers.

Why it ranks #8: The 2-inch muffler names Z900, GSXR750, and CBR650 fitment, but the listing says minor cutting and welding may be needed.

An adjustable stainless-steel adapter spans 38–51mm pipes, giving this YZCHAIN carbon-fiber slip-on broad listed compatibility. The product specifically names Kawasaki Z900, Suzuki GSXR750 and Honda CBR650, while also stating that minor cutting and welding are needed for full installation on most bikes.

The 2-inch slip-on is listed for the Z900, GSXR750 and CBR650, and its adjustable adapter accommodates 38–51mm tubes. That range supports multiple pipe sizes, but the installation caveat matters: the description says most bikes need minor cutting and welding for full installation. The carbon fiber, aluminum and stainless steel construction is stated to withstand 1200°F, while the listing also claims 30% lower weight versus a stock exhaust; those performance claims are product-provided.

Skip it if you need a slip-on requiring no cutting or welding on most bikes; PACEWALKER's EM077 lists a slip-on installation type.

This is for riders with a compatible 38–51mm pipe who can accommodate the stated cutting and welding for full installation on most bikes. The named models and heat-resistance claim are useful, but the installation work is a real boundary.

9. Fast Pro Hexagon Muffler

• Material Type: Aluminum, Stainless Steel, Titanium
• Compatible with Vehicle Type: Atv,Bike,Dirt,Dirt Bike,Motorcycle,Scooter
• Weight: 3.3 lb

Best for: Universal 38–51mm pipe fit.

Why it ranks #9: Its 390mm universal muffler covers 38–51mm pipe diameters and includes hardware, but installation instructions are not included.

A 38–51mm connection range is the core flexibility of this Fast Pro hexagon muffler, which is listed for dirt bikes, street bikes, scooters, ATVs and quads. Its 390mm length and included hardware offer practical details for buyers checking fit and preparing an installation.

The universal listing covers vehicles with 38–51mm pipe diameters, making measurement of the existing exhaust connection the main compatibility step. At 390mm long, the muffler also needs adequate space along the bike’s exhaust route. The package includes an exhaust pipe and hardware, but installation instructions are not included. Its listed materials are aluminum, stainless steel and titanium, giving buyers the supplied construction information when comparing universal slip-on options.

Skip it if you need installation instructions in the package; PACEWALKER's EM077 lists an exhaust pipe, bracket and spring as included components.

This fits buyers seeking a universal muffler for a 38–51mm pipe and who can plan installation without included instructions. Its 390mm length is a key clearance check, and compatibility still depends on the existing pipe diameter.

#10

10. ABCERRSI 28mm Muffler

• Weight: 1.2 lb

Best for: Small-aperture off-road exhausts.

Why it ranks #10: This muffler’s 28mm aperture and 22–32mm buckle range target narrower dirt-bike and ATV connections, limiting broad motorcycle suitability.

A 28mm aperture and 22–32mm buckle range distinguish this ABCERRSI muffler from larger universal slip-ons, targeting dirt bikes and ATVs. Its 260mm length and aluminum construction make the dimensions easy to compare with a compact off-road setup, while a built-in porous baffle and spiral airflow channel are specified.

The 28mm aperture is the central fit check, with an adapter ring supporting 26mm and 30mm original interfaces; the buckle range is 22–32mm. Those dimensions help buyers assess whether the muffler matches their existing connection before fitting. The 260mm body is compact by its listed length, and its built-in porous baffle plus spiral airflow channel are described as optimizing torque at 3000–6000rpm. The listing claims a 12% low-torque increase versus a straight-through type.

Skip it if you need a 38–51mm pipe connection; Fast Pro's F17130008 lists that broader universal diameter range.

This suits dirt-bike and ATV owners whose connection matches its 28mm aperture or supported 26mm/30mm interfaces. Its compact 260mm length and stated low-to-mid-speed torque focus are relevant, but larger pipe connections fall outside the listed sizes.
