PACEWALKER Quiet Exhaust For Street And Scooters

Best for street and sport motorcycles that run on 38-51mm diameter pipes. This model uses a lightweight aluminum body with a stainless steel connector and a removable DB killer to vary sound. The overall length is 365mm, with a 51mm slip-on connection. Suitable for riders seeking a balance between quieter operation and respectable exhaust note. Caution: sound profile changes noticeably when the DB killer is removed, so verify local noise regulations before riding in noise-sensitive areas.
Universal 48mm Exhaust Muffler Silencer (2 Pack)

Best for riders who want durable, high-temperature-resistant silencers with value in mind. Constructed from stainless steel, designed to withstand road wear and heat without warping. The two-pack option lets you replace or tune performance across multiple bikes. Caution: installation may require compatible hardware and proper sealing to prevent leaks, especially on older systems.
Universal 51mm DB Killer Exhaust Silencer

Best for riders of Harley, Honda, Kawasaki, Suzuki, and Yamaha motorcycles seeking a universal 51mm fit with noise reduction. Stainless steel construction and a high-temperature coating improve longevity and rust resistance. It’s a practical choice when you want to lower decibels without sacrificing too much exhaust flow. Caution: some bikes may require modifications for a perfect fit; check diameter compatibility and mounting hardware.
1.1 Inch Muffler For 50cc–125cc Dirt Bikes

Best for smaller bikes, pit bikes, and mini ATVs. This muffler is compatible with a wide range of 50cc–125cc Chinese dirt bikes and some minibikes with minor adaptation. It’s robust for frequent off-road use and can help reduce noise while preserving essential exhaust flow. Caution: installation notes indicate the pipe body should not be welded, so secure mounting is essential to avoid damage.
Universal 1.5″ Inlet Carbon Fiber Look Muffler

Best for versatile use across dirt, street, and scooter applications. This muffler fits pipes with a 38mm (1.5 inch) diameter and includes a removable DB killer for adjustable sound. It combines aluminum and stainless steel construction with a carbon fiber appearance for a sportier look. Caution: cosmetic carbon fiber finish is aesthetic; verify actual material if that matters for durability in harsh environments.
Buying Guide: Quiet Exhausts For Motorcycles
Key considerations help buyers pick the right quiet exhaust. First, determine your bike’s pipe diameter to ensure a proper fit—common sizes include 38mm, 51mm, and 48mm. Consider whether you want a removable DB killer for adjustable noise, or a fixed silent design for consistent operation. Material matters: stainless steel resists rust and heat, while aluminum keeps weight down. Durability and compatibility with dirt bikes, street bikes, or sport bikes influence long-term satisfaction. For riders in noise-sensitive neighborhoods, verify local regulations before installing a quieter exhaust.
Fitment and installation are practical concerns. Some exhausts are universal and require adapters or clamps; others specify exact models or broad compatibility. Look for high-temperature coatings to prevent corrosion and verify that the product won’t interfere with performance at your engine’s RPM range. If possible, choose options with multiple dampening levels, so you can fine-tune the sound to your preference and riding situation.
FAQ
- Will these exhausts always reduce noise? Most listed silencers reduce sound output, especially with DB killers installed; actual results vary by bike and exhaust system.
- Do I need professional installation? It depends on your bike and the exhaust; universal models may require basic tools and sealing techniques, while some setups require clamps or quick fits.
- Can I run a DB killer while riding on the street? Yes, if local noise regulations permit; the killer reduces decibels but may affect exhaust flow and performance.
- Will quieter exhaust affect engine performance? Some designs maintain or improve efficiency while reducing noise; others may alter backpressure slightly, so assess compatibility with your bike’s tuning.
- Are carbon fiber-look exhausts durable? They provide aesthetics and light weight, but true material durability depends on construction; ensure the core is metal for heat resistance.
- What should I check before buying? Verify pipe diameter, fitment, whether a DB killer is included, and ease of installation on your specific model.
