Best Motorcycle Exhaust Slip Ons for 38–51mm Pipes and Harley Touring

#1 · Best Overall

1. PACEWALKER 2-Inch Carbon Fiber

• Weight: 1.1 kg
• Material Type: Carbon Fiber, Stainless Steel
• Compatible with Vehicle Type: Motorcycle
• Inlet Connection Size: 2 in

Best for: Compact carbon-fiber slip-on.

Why it ranks #1: Lists a 2-inch/51mm connection and 160mm overall length, with carbon-fiber and stainless-steel materials for a clearly specified universal slip-on.

At 160 mm long with a 2-inch/51 mm connection, this PACEWALKER carbon-fiber slip-on gives buyers two concrete dimensions for checking space and inlet fit. Its carbon fiber and titanium-alloy construction, joined by a stainless-steel connector, targets riders seeking a compact muffler with a distinctive material mix.

The 160 mm overall length helps riders assess available exhaust space before installation, while the 51 mm connection narrows the intended inlet size. PACEWALKER lists carbon fiber and a titanium-alloy body with a stainless-steel connector; its description associates carbon fiber with heat resistance and the construction with strength. The slip-on format suits an existing exhaust connection, but the supplied information does not list a removable DB killer or provide a broader inlet range.

Skip it if you need an inlet range spanning 38–51 mm; PACEWALKER’s grilled-blue 1.5–2-inch model lists that range.

This is a fit-focused choice for riders whose exhaust accepts a 51 mm connection and whose available space suits its 160 mm length. Choose it for the carbon-fiber material mix, while recognizing the listing does not specify a removable baffle.

#2 · Broadest Inlet Range

2. PACEWALKER Grilled Blue

• Weight: 1.5 kg
• Material Type: Stainless Steel, Titanium
• Compatible with Vehicle Type: Motorcycle
• Inlet Connection Size: 38-51 millimeters

Best for: Removable-baffle sound choice.

Why it ranks #2: Specifies a 38–51mm inlet and a removable DB killer; titanium alloy and a stainless connector set it apart among universal options.

A removable DB killer lets riders change the sound configuration of this PACEWALKER muffler, a useful distinction for those who want that option in a universal slip-on. Its 38–51 mm inlet range covers multiple stated motorcycle and scooter pipe diameters, while the baked-blue finish adds a visible gradient treatment.

The titanium-alloy body and stainless-steel connector combine the listed materials in a format intended for 38–51 mm pipes, helping buyers assess both construction and inlet compatibility. Removing the DB killer offers a different sound effect, according to the listing, so riders can choose between configurations rather than receiving a fixed baffle setup. The double-head baking-blue process is described as anti-rust and higher-strength, with a gradient appearance as a styling benefit.

Skip it if you need published body dimensions or included mounting hardware details; TBVECHI’s ASGI3-03KS lists dimensions and complete accessories.

Pick this PACEWALKER when a removable baffle and gradient blue finish matter alongside a 38–51 mm inlet. The listing leaves overall dimensions and installation hardware unspecified, so those details may matter when planning a close-clearance or hardware-dependent fit.

#3 · Removable DB Killer

3. LEIMO KPARTS Carbon Fiber

• Weight: 1.37 kg
• Material Type: Aluminum, Stainless Steel
• Compatible with Vehicle Type: Bike,Motorcycle,Dirt Bike,Scooter,Atv,Scooters
• Inlet Connection Size: 1.5 in

Best for: Broad-diameter removable-baffle option.

Why it ranks #3: Covers 38–51mm pipes and lists a removable DB killer, with aluminum and stainless-steel construction for varied bike styles.

A removable DB killer provides this LEIMO KPARTS slip-on with a changeable sound configuration, while its stated 38–51 mm pipe range covers several motorcycle and off-road vehicle types. The carbon-fiber finish over aluminum and stainless steel gives buyers a material combination aimed at lower overall weight and corrosion resistance.

The 38–51 mm compatibility range is listed for dirt bikes, street bikes, scooters, ATVs, and quads, helping riders compare the inlet to a wider variety of exhaust setups. Its removable DB killer offers different sound effects, so the baffle can be taken out when the rider wants the alternate configuration. Aluminum and stainless steel beneath the carbon-fiber finish are described as corrosion-resistant and rustproof; the listing does not give a muffler length.

Skip it if you need a published overall length for checking tight exhaust space; PACEWALKER’s 2-inch carbon-fiber model lists a 160 mm length.

Consider this LEIMO KPARTS muffler if your pipe falls within 38–51 mm and you want a removable baffle across several vehicle types. Its length is not supplied, so confirm that the available mounting space suits your setup before choosing.

4. YZCHAIN Carbon Fiber Muffler

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

Best for: Adjustable-adapter universal fit.

Why it ranks #4: States a 38–51mm adjustable adapter range and names Z900, GSXR750 and CBR650 fitment, though installation may need cutting or welding.

An adjustable stainless-steel adapter spans 38–51 mm pipes, giving this YZCHAIN carbon-fiber slip-on a broad starting range for dirt bikes, street bikes, scooters, ATVs, and quads. Its listed Z900, GSXR750, and CBR650 applications make it especially relevant to riders with those models, while the adapter accommodates other listed pipe diameters.

The 2-inch slip-on format and adjustable adapter let riders work across the stated 38–51 mm tube range, though the listing says most bikes need minor cutting and welding for full installation. Carbon fiber, aluminum, and stainless steel construction is rated to withstand 1200°F, a useful heat-resistance specification for exhaust service. The listing also claims 30% lower weight versus a stock exhaust, connecting weight reduction with improved acceleration; it does not provide a measured test method.

Skip it if you need an installation requiring no cutting or welding; the listing says most bikes need those steps for full installation.

Choose this YZCHAIN muffler if your motorcycle uses a 38–51 mm pipe and you value its heat-rated composite construction and claimed weight reduction. Allow for possible cutting and welding; the adapter range alone does not make installation modification-free.

5. TBVECHI Carbon Fiber Muffler

• Weight: 1.2 kg
• Material Type: Aluminum
• Compatible with Vehicle Type: Motorcycle

Best for: Named sportbike 2-inch fit.

Why it ranks #5: Specifies a 2-inch inlet and names Z900, GSXR750 and CBR650 compatibility, making its connection detail useful for measured-pipe matching.

A stated 2-inch inlet and named Kawasaki Z900, Suzuki GSXR750, and Honda CBR650 fitment make this TBVECHI carbon-fiber slip-on especially relevant to those motorcycles. Its 10.82-inch length and real-carbon-fiber construction give riders both a physical size and a material detail to weigh against their existing exhaust layout.

The 2-inch inlet targets the pipe size named for the listed sportbike applications, helping buyers narrow compatibility rather than relying only on the universal-accessory description. The 10.82 x 4.52 x 4.33-inch dimensions provide space-planning measurements before mounting. Real carbon fiber is specified for the muffler, and the listing also names CNC-machined billet aluminum; together, these details describe its material construction. The supplied facts do not state a broader inlet range or a removable baffle.

Skip it if you need a listed 38–51 mm pipe range; PACEWALKER’s grilled-blue 1.5–2-inch muffler specifies that broader inlet span.

This TBVECHI suits riders with a 2-inch exhaust connection, particularly owners of the named Z900, GSXR750, or CBR650 applications. Use its listed dimensions to assess clearance, and do not assume the inlet covers smaller pipes.

#6 · Included Mounting Hardware

6. Generic Carbon Fiber Muffler

• Weight: 1.17 kg
• Material Type: Stainless Steel
• Compatible with Vehicle Type: Motorcycle
• Inlet Connection Size: 2 in

Best for: Quick-removal 51 mm setup.

Why it ranks #6: Gives a 2-inch connection and 210mm length, and lists a spring puller and fixing rings for mounting and removal.

Included spring puller and fixing rings support mounting and removal of this 8.26-inch carbon-fiber slip-on, making it a practical option for riders who want the listed hardware on hand. Its 2-inch/51 mm connection and stated Z900, GSXR750, and CBR650 fitment focus the choice on compatible setups.

The 210 mm overall length and 51 mm inlet give buyers concrete dimensions to compare with their exhaust layout, while the slip-on format keeps the unit distinct from a full exhaust system. The included spring puller and fixing rings support the stated easy mounting and removal workflow. The listing says the muffler can effectively reduce noise and names carbon fiber, stainless steel, and aluminum in its construction, but gives no noise level or quantified reduction.

Skip it if you need a stated 38–51 mm adjustable pipe range; YZCHAIN’s ACQ-ADC-HHL795 lists that adapter range.

This Generic slip-on suits riders whose setup matches its 2-inch inlet and who value included mounting and removal hardware. Check the actual exhaust dimensions against the 210 mm body and inlet, since the listing does not specify a wider diameter range.

7. DREAPATS Universal Muffler

• Material Type: Stainless Steel
• Compatible with Vehicle Type: Bike,Motorcycle,Dirt Bike,Atv
• Inlet Connection Size: 5.1 centimeters

Best for: Hardware-included universal setup.

Why it ranks #7: Targets 38–51mm exhausts and lists a DB killer, springs, hooks, clamps and a connecting pipe, but some fits need modification or welding.

A universal connect pipe, DB killer, springs, hooks, and stable clamps come with this DREAPATS slip-on, giving buyers several mounting and baffle components in one listed package. Its stated 38–51 mm compatibility spans motorcycles, dirt bikes, ATVs, and scooters, subject to the pipe and modification requirements.

The product is specified for 51 mm/2-inch link pipes or downpipes, and the listing says smaller muffler connections within 38–51 mm require modification and welding. That caveat matters when planning installation despite the supplied universal connect pipe and hardware. Stainless steel is described as heat-resistant and corrosion-resistant, while the included DB killer/baffle offers a supplied silencing component. The listing also calls the exhaust loud, but provides no measured sound level or output figure.

Skip it if you require installation without modification or welding on a smaller pipe; YZCHAIN’s ACQ-ADC-HHL795 specifies an adjustable adapter, though it also notes most bikes need cutting and welding.

Choose this DREAPATS option if you want the listed connection pipe, clamps, springs, hooks, and baffle for a compatible setup. Its 51 mm fit guidance and smaller-pipe welding caveat make careful installation planning essential.

#8 · Harley Touring Fit

8. SHARKROAD 2017-Up Touring

• Weight: 7.05 kg
• Material Type: Aluminum
• Compatible with Vehicle Type: Touring Electra Glide 2017-2023, Touring Road…
• Inlet Connection Size: 1.75 in

Best for: 2017–2023 Harley Touring fit.

Why it ranks #8: Provides model-specific fitment for 2017–2023 Harley Touring models, with a 1.75-inch inlet and 4.4-inch outlet; it excludes trikes.

Specific fitment for 2017–2023 Harley Touring models—including Road King, Street Glide, Road Glide, Electra Glide, and Ultra Limited—sets this SHARKROAD 4.4-inch muffler apart from universal slip-ons. Its listed 1.75-inch inlet and 4.4-inch outlet give Touring owners key dimensions to check against their exhaust setup.

The model-year and Touring-family fitment makes this a targeted replacement choice rather than a general motorcycle muffler; the specifications list five named models across 2017–2023. A 1.75-inch inlet provides a concrete connection dimension, and the 4.4-inch outlet identifies the muffler size at the exit. The aluminum construction is specified in the product data. The description explicitly excludes Trike models, a boundary buyers should account for before selecting this application-specific part.

Skip it if you have a 2009–2016 Harley Touring model with a stock 1.75-inch header; SHARKROAD’s 4.4-inch Chrome Slip On Mufflers list that earlier fitment.

This SHARKROAD muffler is for owners of the listed 2017–2023 Harley Touring models who want a 4.4-inch outlet. It is not listed for Trikes, so model family and year range are central fit boundaries.

9. SHARKROAD Chrome Slip-Ons

• Material Type: Chrome
• Compatible with Vehicle Type: Motorcycle
• Inlet Connection Size: 1.75 in

Best for: Earlier Harley Touring pair.

Why it ranks #9: Specifies a pair for 2009–2016 Harley Touring models with stock 1.75-inch header pipes, while excluding later M8 models and trikes.

A complete package includes two slip-on pipes and necessary installation hardware, making this SHARKROAD chrome set a pair-focused choice for compatible Harley Touring motorcycles. Its specified fitment covers 2009–2016 models with stock 1.75-inch outside-diameter header pipes, including Street Glide, Road King, and Road Glide.

The two-pipe package and included hardware support replacing both sides without sourcing the listed installation pieces separately. Chrome construction supplies the stated finish, while the 1.75-inch header requirement gives buyers a precise connection measurement to verify. Fitment names 2009–2016 Touring families such as Ultra Classic and Electra Glide, but the listing excludes 2017-up M8 Touring models, Tri-Glide, Freewheeler, and other applications. Those limits make year and model checks essential.

Skip it if you ride a 2017–2023 Harley Touring model other than a Trike; SHARKROAD’s MP17 lists those Touring years and models.

Pick this SHARKROAD pair for a 2009–2016 Harley Touring bike with stock 1.75-inch O.D. header pipes when you want both mufflers and hardware together. Its stated exclusions rule out later M8 models and listed trikes.

#10

10. Tesmirror Slash Cut Muffler

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

Best for: Reducer-equipped retro chopper fit.

Why it ranks #10: Its slash-cut chopper and cafe-racer design and reducer for several pipe sizes are less directly aligned with a conventional motorcycle slip-on search.

An included reducer accommodates four stated pipe sizes—1-3/8, 1-1/2, 1-5/8, and 1-3/4 inches—giving this Tesmirror slash-cut muffler a clear fit range for chopper and cafe racer projects. Its chrome-plated steel construction and retro styling suit riders seeking a traditional exhaust appearance.

The included reducer supports the four listed pipe diameters, while the claimed left- or right-side fit gives riders flexibility when placing this one-piece muffler. Tesmirror describes the precision-cast design as easy to install and a direct replacement, connecting its construction with a straightforward installation workflow. High-grade steel and durable chrome plating supply the listed materials and finish; the retro slash-cut style is associated with the product’s stated exhaust sound, though no sound level is provided.

Skip it if you want a broad 38–51 mm slip-on for several vehicle types; LEIMO KPARTS’ CF-SO-UNI-365 lists that pipe range.

This Tesmirror is suited to chopper or cafe racer owners whose pipe matches one of its four reducer sizes and who want a slash-cut chrome look. Its sound description is unquantified, so it is not a choice for buyers selecting by a stated decibel level.
