Best Motorcycle Exhaust Pipes for Universal and Harley Fitments

#1 · Best Overall

1. PACEWALKER Motorcycle 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 #1: Its 365 mm slip-on covers stated 38–51 mm pipes and includes a reducer adapter, mounting clamp and removable DB killer for sound adjustment.

A removable DB killer is the key differentiator on this 365 mm PACEWALKER muffler, letting riders choose between sound effects rather than committing to one setup. Its aluminum body and stainless steel connector pair with a 38–51 mm adapter range for a broad selection of motorcycles and scooters.

The included 38–51 mm adapter and mounting clamp support slip-on installation across pipes in that diameter range, while the 51 mm connection specification identifies the muffler’s inlet. A removable DB killer gives riders a way to change the sound character; the listing describes the result as deep and slightly throaty, not terribly loud. At 365 mm long, it is a substantial replacement component, so check available space along the exhaust run before fitting.

Skip it if you need a slash-cut chrome tip for a chopper or cafe racer; Tesmirror’s stainless steel slash-cut muffler matches that style.

For riders seeking an adjustable-sound slip-on for a street bike, sport motorcycle, or scooter with a 38–51 mm pipe, this offers a broad fit range. Its 365 mm body still needs adequate exhaust clearance.

#2 · Best Steel Option

2. FLYPIG Adjustable Exhaust

• Material Type: Stainless Steel
• Compatible with Vehicle Type: ATV, Dirt Bike, Quad, Scooter, Street Bike
• Weight: 0.82 kg

Best for: Adjustable-diameter stainless slip-on.

Why it ranks #2: Stainless steel construction and an included 38–51 mm adapter suit riders who need adjustable inlet fitment across the listed diameter range.

An included 38–51 mm stainless steel adapter is the defining feature of this FLYPIG exhaust, allowing its 51 mm inlet body to connect to smaller listed pipe diameters. That adjustable fit range extends its stated use across street bikes, scooters, dirt bikes, ATVs, and quads.

Rather than being limited to a fixed 51 mm connection, the exhaust comes with an adapter for pipes between 38 and 51 mm, making the existing pipe diameter central to fit. Stainless steel construction is described as corrosion resistant and rust proof, a useful property for an exposed exhaust component. The package also lists related mounting accessories, supporting the installation workflow. Measure the existing pipe before ordering, as FLYPIG specifically calls for diameter measurement to choose the proper connection.

Skip it if you need a complete Harley LAF set for forward controls; mhanewv’s B0FL7BW1RN lists Harley model applications and a 2-inch LAF setup.

This suits riders seeking a stainless slip-on across a 38–51 mm pipe range, particularly when the bike falls within the listed vehicle types. Measure the existing connection and use the included adapter where needed.

#3 · Removable DB Killer

3. 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: Carbon-finish adjustable universal muffler.

Why it ranks #3: This aluminum-and-stainless universal muffler fits stated 38–51 mm pipes and includes a removable DB killer for different sound effects.

A removable DB killer gives the LEIMO KPARTS carbon-finish muffler a sound-adjustment option across its listed 38–51 mm fit range. The aluminum and stainless steel construction is described as corrosion resistant, while the universal application spans motorcycles, dirt bikes, scooters, ATVs, and quads.

The 38–51 mm range supports use on several bike and powersports categories, provided the exhaust connection falls within that diameter span. Its removable DB killer lets riders alter the sound effect rather than settle for a fixed configuration. The aluminum and stainless steel construction is described as durable, corrosion resistant, and rustproof; the product description also presents the design as reducing overall weight. As a slip-on muffler, it is intended to connect at the existing exhaust pipe rather than replace a full system.

Skip it if you need a specified 368 mm dual-outlet muffler with a bracket and spring; PACEWALKER’s B0FJ4YMHBS lists those details.

This suits riders seeking a carbon-finish slip-on with removable sound control for a 38–51 mm connection. The supplied facts do not give an overall length, so confirm available exhaust space from the product dimensions before choosing.

#4 · Longest Listed

4. 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: Hardware-included 390 mm universal muffler.

Why it ranks #4: Its listed 390 mm length is longer than the other specified universal slip-ons, and its 38–51 mm fit spans several vehicle types.

At 390 mm long, Fast Pro’s hexagon muffler offers a longer slip-on option for riders with compatible 38–51 mm pipes. Its listed applications span dirt bikes, street bikes, scooters, ATVs, and quads, and the package includes installation hardware for the exhaust swap.

The stated 38–51 mm connection range broadens its potential use across several motorcycle and powersports categories, from scooters to dirt bikes. Fast Pro includes hardware with the exhaust pipe, so buyers have components supplied for installation rather than a bare muffler. The 390 mm body is longer than many compact slip-on choices, making available space and the existing exhaust layout practical considerations. Installation instructions are not included, so fitting may require the buyer to work out the procedure independently.

Skip it if you want a muffler with documented sound adjustment; PACEWALKER’s B074CVHHGC has a removable DB killer.

Choose this for a compatible 38–51 mm bike or ATV when a 390 mm hexagon muffler and included hardware suit the installation. It is less suitable for buyers who need supplied installation instructions.

#5 · Dual-Outlet Design

5. FLYPIG Dual-Outlet Muffler

• Material Type: Aluminum, Stainless Steel
• Compatible with Vehicle Type: Motorcycle
• Weight: 1.13 kg

Best for: Dual-outlet 38–51 mm slip-on.

Why it ranks #5: The 368 mm slip-on has a dual-outlet design and stated 38–51 mm compatibility, with accessories included for installation.

A dual-outlet design distinguishes this 368 mm FLYPIG muffler, giving compatible bikes a defined tailpipe layout in a universal slip-on format. Its 38–51 mm fit range is listed for motorcycles, dirt bikes, scooters, quads, ATVs, and sport bikes, including several named models.

The 38–51 mm slip-on connection range covers multiple vehicle categories, and the listing names Yamaha YZF-R6, BMW S1000RR, and Honda CBR250RR among examples. Aluminum and stainless steel construction pairs with stainless steel clamps, while the package includes the exhaust pipe and accessories. The supplied warning says metal edges may feel sharp during handling and recommends gloves during installation. It also names Honda CBR250R 2011 and Honda CBR1000rr 2008 as incompatible, making model-specific fit checks important.

Skip it if you need a 38–51 mm adapter explicitly listed for stainless steel; FLYPIG’s B07TZGZBZH includes one.

This suits riders seeking a dual-outlet slip-on for a compatible 38–51 mm connection, including the named Yamaha, BMW, and Honda examples. Avoid the two Honda models identified as incompatible, and wear gloves when handling its edges.

6. 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 #6: This 368 mm universal slip-on lists 38–51 mm compatibility and includes a bracket and spring alongside its dual-outlet design.

A dual-outlet tailpipe sets this 368 mm PACEWALKER muffler apart, offering a distinctive exhaust layout for compatible motorcycles and scooters. Its 38–51 mm slip-on range covers multiple pipe diameters, and the package lists a bracket and spring alongside the exhaust pipe.

The 38–51 mm connection range makes this a candidate for varied motorcycle and scooter exhaust sizes, while the slip-on format identifies its installation style. PACEWALKER lists the dual-outlet design as a feature intended to reduce overall weight and describes the sound as outstanding. The included bracket and spring provide mounting components, though the product facts do not specify a DB killer or an adjustable sound feature. At 368 mm long, it also needs room along the exhaust path.

Skip it if you want a removable DB killer for sound adjustment; PACEWALKER’s B074CVHHGC explicitly includes one.

This is suited to riders looking for a dual-outlet slip-on for a motorcycle or scooter with a 38–51 mm pipe. Check the 368 mm body length and mounting arrangement against available space on the bike.

#7

7. JFG RACING Dirt Bike Exhaust

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

Best for: 38 mm dirt-bike slip-on option.

Why it ranks #7: It is a full slip-on aimed at named dirt-bike models, with listed 38 mm inlet and outlet connections; broader fitment detail is limited.

A 38 mm inlet and outlet specification gives this JFG RACING slip-on a clear sizing target for compatible dirt bikes. The listing names the HAWK 250, CRF230F, CRF150F, and TBR7, so riders can weigh those applications against the stated connection dimensions.

The 38 mm inlet and outlet provide concrete connection specifications for checking an existing exhaust layout, while the named HAWK 250, CRF230F, CRF150F, and TBR7 applications help narrow the intended audience. Its listed material composition includes aluminum, stainless steel, and titanium. The title identifies it as a full slip-on exhaust, but the supplied details do not give an overall length, included hardware, or installation instructions, so buyers should not assume those specifics from the available product facts.

Skip it if you need an adapter for pipes from 38 to 51 mm; FLYPIG’s B07TZGZBZH includes a 38–51 mm stainless adapter.

This is for dirt-bike riders whose intended setup matches the named applications and 38 mm inlet and outlet specifications. The supplied listing gives limited installation detail, so those dimensions are the clearest fit boundary.

#8

8. RongTengKeJi LAF Pipes

• Compatible with Vehicle Type: Motorcycle

Best for: Baffle-free Harley straight-pipe set.

Why it ranks #8: The Harley-oriented bolt-on set includes two pre-bent pipes, flanges, gaskets, clamps and heat shields, but fitment is limited to specified models.

A baffle-free straight-pipe layout gives this RongTengKeJi set its defining sound character: the listing calls it a super-loud roar. The 2-inch chrome-plated pipes target a range of 1984–2023 Harley families, with a complete set of mounting and heat-shield components included.

The set includes two pre-bent 2-inch pipes, flanges, sealing gaskets, long bolts, clamps, heat shields, and a mounting bracket, giving buyers multiple installation components in one package. Its bolt-on installation type identifies the intended mounting approach, while the chrome-plated finish is described as resisting rust through rain, mud, and high temperatures. Fit notes specify forward-control use for 1986-and-up Sportster models, so that application boundary should be checked before treating the broader model list as universal.

Skip it if you want a described deep, not-terribly-loud sound; PACEWALKER’s B074CVHHGC lists that character and a removable DB killer.

This set fits Harley riders seeking chrome 2-inch straight pipes and a baffle-free roar, with installation pieces supplied. Its loud sound and stated forward-control Sportster fit boundary make it unsuitable for every setup.

#9

9. mhanewv LAF Exhaust Pipes

• Weight: 9.44 lb

Best for: Forward-control Harley LAF pipe set.

Why it ranks #9: These 2-inch pipes target listed Harley families, but the seller notes forward-control restrictions and possible modifications on some models.

A stated 1984–2023 Harley application range makes these 2-inch LAF pipes a focused option for Sportster, Softail, Dyna, Touring, Chopper, and Bobber builds. Their chrome plating is presented as rust resistant through exposure to rain, mud, and high temperatures.

The LAF format is listed for several Harley families, but the fit notes make control placement decisive: the pipes are for forward-control models and not mid-controls that obstruct them. Chrome plating is described as resisting rust in wet and muddy use and at high temperatures, giving the exterior finish a practical role as well as a polished appearance. The listing also warns that some Dyna or Touring applications may need modifications or adjustments, and the supplied bracket does not fit every model.

Skip it if you need a broad universal slip-on for a scooter or dirt bike; FLYPIG’s B07TZGZBZH covers 38–51 mm pipes across those vehicle types.

These pipes fit Harley riders with a listed model and forward controls who want a 2-inch LAF setup. Control interference and model-specific bracket or modification needs remain key installation boundaries.

#10

10. Tesmirror Slash-Cut Muffler

• Material Type: Stainless Steel
• Compatible with Vehicle Type: Motorcycle
• Weight: 1.63 kg

Best for: Slash-cut chopper and cafe-racer tip.

Why it ranks #10: Its chrome-plated steel tip fits several pipe sizes with a reducer, but the listing describes a muffler tip rather than a complete exhaust system.

A slash-cut outlet gives the Tesmirror muffler its defining retro look for chopper and cafe-racer builds, while its included reducer accommodates several pipe sizes. The stainless steel construction and chrome plating suit riders seeking a metal exhaust tip with a direct-replacement installation approach.

The listed fit range covers 1-3/8, 1-1/2, 1-5/8, and 1-3/4 inch pipes, with a reducer included to bridge those sizes. Tesmirror specifies left- and right-side use, providing flexibility when choosing the mounting side. Its precision-cast construction is described as supporting straightforward installation, and the stainless steel with chrome plating gives the slash-cut piece a durable finished surface. The listing identifies it as a one-piece muffler pipe for chopper and cafe-racer styling.

Skip it if you have a 38–51 mm slip-on pipe and want a removable DB killer; PACEWALKER’s 365 mm muffler includes one.

This suits chopper and cafe-racer owners who want a slash-cut, chrome-plated tip and have a pipe within the listed 1-3/8 to 1-3/4 inch range. Confirm that range against the intended connection before installation.
