FMF - 4-Stroke Race PackingFMF 4 Stroke Race Packing FMF 4 Stroke Race Packing is the go to choice for riders who want to keep their exhaust performing like new. Over time, muffler packing breaks down from heat and vibration, which can rob your bike of power and give it that blown out sound.

FMF - 4-Stroke Race Packing
FMF 4-Stroke Race Packing is the go-to choice for riders who want to keep their exhaust performing like new. Over time, muffler packing breaks down from heat and vibration, which can rob your bike of power and give it that blown-out sound. A fresh repack restores throttle response, improves power delivery, and brings back that clean FMF tone your exhaust was designed to have.
Why we like it: FMF didn’t just throw some fiberglass together — this is a purpose-built, four-layer system engineered for high-output 4-stroke engines. It combines stainless steel wool, a high-density woven temperature barrier, and FMF’s exclusive red performance material to handle extreme heat and deliver long-lasting results. It resists blowout and stays effective ride after ride.
Why it’ll work for you: it’s made specifically for FMF 4.1 mufflers and recommended for riders who want consistent power and sound quality. Repacking every 20–30 hours of use (under normal conditions) keeps your exhaust flowing properly and your motor running at peak efficiency. Strong, durable, and race-proven — FMF 4-Stroke Race Packing keeps your bike sounding crisp and performing its best.
Key Features:
- Developed for high-output 4 Strokes.
- 4-layer design - stainless steel wool, high-density woven temperature barrier and then FMF's exclusive packing material.
- Long lasting and resistant to blowing out.
- FMF recommends repacking your muffler every 20-20 hours under normal use when properly jetted
- FMF Recommended packing for 4.1 mufflers
