JFG RACING Slip-On Motorcycle Exhaust Muffler 1.5–2" Universal (Carbon-Fiber Style) — Stainless Steel Core, 38–51mm Adapter

The JFG RACING slip-on exhaust is a universal 1.5–2" motorcycle muffler designed to replace or upgrade stock silencers on dirt bikes, scooters, ATVs and street bikes with 38–51 mm outlet pipes.

This compact, bolt-on muffler combines a stainless-steel core with a carbon-fiber–style vinyl wrap to deliver corrosion resistance, lighter weight than many OEM units, and a sportier look. It ships with a welded stainless-steel adapter to bridge pipe diameters from 38 mm up to 51 mm and includes mounting hardware so most installs require only basic tools. Professional installation is recommended for a secure fit and correct alignment with your exhaust system.

Will this muffler fit my bike's exhaust pipe?

Yes — the JFG RACING slip-on is built as a universal unit that adapts to a wide range of bikes. It accommodates pipe outlets measuring 38 mm to 51 mm using the included stainless-steel welding adaptor.

• Connection diameter: 51 mm (2.0") as the muffler inlet.
• Adapter allows fitment to pipes from 38 mm to 51 mm.
• Common fits: dirt bikes, pit bikes, scooters, ATVs, quads and many street bikes.

How difficult is installation and what comes in the box?

• Requires basic tools; welding or professional fitment can ensure leak-free sealing.

What materials and dimensions should I expect?

The body uses stainless-steel construction wrapped in a carbon-fiber–color vinyl for a sport finish and improved resistance to heat and weather. The unit is compact and engineered for universal compatibility while keeping weight down.

• Overall length: 370 mm (approx. 12.8 inches).

What performance or aesthetic changes will I notice?

This slip-on muffler mainly affects sound character and rear-end styling rather than engine power. Expect a crisper exhaust tone and a sleeker, aftermarket look; any performance gains depend on the bike’s tuning and whether further exhaust modifications are made.

• Delivers a sportier visual profile compared to many stock silencers.
• Changes exhaust note to a more aggressive, free-flowing sound.
• May require retuning on some bikes to optimize air/fuel ratios.
• Not marketed as a power-increasing, guaranteed-performance part.
