Universal 1.5-2″ Inlet Hexagon Exhaust Muffler Pipe Slip On Scooter Motorcycle ATV Dirt Street Bike
Best for riders who want a universal, no-frills muffler with wide compatibility. The hexagon muffler supports 38-51mm pipe diameters and arrives with necessary hardware for straightforward installation. It’s suitable for dirt bikes, street bikes, scooters, ATVs, and quads. A potential limitation is the lack of installation instructions, so buyers should be prepared to reference general slip-on mounting steps.
PACEWALKER Slip On Muffler with Detachable DB Killer (Plating)
Best for riders seeking sound customization and corrosion resistance. This universal muffler uses a stainless steel sleeve and connectors with a plated finish to resist rust and add brightness. It accommodates 38-51mm exhaust pipes and features a detachable DB killer for variable volume. Choose this if you want a brighter, more aggressive sound without sacrificing durability; beware that performance can vary based on your bike’s exhaust routing and header configuration.
Carbon Fiber Slip-On Exhaust Muffler (Black)
Best for performance-focused riders who want a sleek, carbon fiber look. This slip-on has a 51mm inlet, is easy to mount with included springs and rings, and aims to reduce noise while delivering an assertive tone. It’s suited for sport bikes like Z900, GSXR750, and CBR650-class models that benefit from a lightweight, streamlined silhouette. A limitation is that exact fitment can depend on the bike’s routing and heat shielding; verify clearance before purchase.
PACEWALKER Slip On Muffler in Grilled Blue
Best for riders who want a gradient blue finish and enhanced aesthetics. The titanium alloy body with a double-head blue finish not only looks stylish but also offers good strength. It supports a universal fit for 38-51mm pipes and includes a detachable DB killer for optional loudness. This model is ideal for riders prioritizing style and customization; consider its finish durability under prolonged heat exposure in aggressive riding conditions.
PACEWALKER Exhaust Tips 1.5-2″ Inlet (Dual Outlet)
Best for riders who want reduced weight with a dual-outlet design for maximum performance and a louder exhaust note. The dual outlets, 38-51mm slip-on, are designed to optimize exhaust flow and tone. It’s a good pick for street and sport bikes seeking a distinctive, aggressive sound. If your bike’s heat shielding is tight, ensure there’s adequate clearance around dual outlets to avoid contact with components.
Buying Guide
Key considerations for choosing a loud motorcycle exhaust slip-on:
- Pipe diameter compatibility: Most universal slip-ons cover 38-51mm; confirm your bike’s exhaust diameter before buying.
- Sound customization: Some models include a detachable DB killer for louder or quieter operation. Decide if you want adjustable volume.
- Material and finish: Stainless steel with plating or titanium alloys affect durability and aesthetics; carbon fiber looks are lighter and sportier but may be costlier.
- Installation ease: Some come with hardware; others require additional components or professional mounting. Consider your DIY comfort level.
- Weight and performance: Slip-ons can reduce or alter weight and backpressure; assess whether you expect a noticeable tone change or modest gain.
- Aesthetics and compatibility: Dual outlets, color finishes (blue titanium, plating), and carbon fiber styling affect visual match with your bike.
Practical comparison tips
- For universal fit, prioritize models explicitly listing 38-51mm compatibility and included mounting hardware.
- If you ride a sport bike and want a distinctive look, consider plated or blue titanium finishes for sharper styling.
- When choosing for sound, start with a model offering a detachable DB killer to test different sound levels.
