Did you know a freshly packed silencer or muffler actually restores power?

Developed for high output 4 strokes, our revolutionary Premier Multi-layer 4 stroke Silencer Packing is comprised of space age, sound-absorbing materials for maximum sound absorption and durability! The first layer consists of a high purity stainless wool shrouded by a aerospace grade stainless screen. A treated high density temperature barrier is encased with an outer layer of FMF’s exclusive silencer packing material. This is the ultimate lightweight and extremely durable 4 stroke packing!

Our Performance Packing is comprised of fine, blended interwoven fiberglass fibers made to FMF’s specifications for high heat resistance, great sound attenuation and optimum performance and longevity. Look for FMF’s distinctive red performance packing.

Our Standard Fiberglass Packing is economical and best suited for non-high performance situations.
