Q Stealth Don Emler headed up the Q-Stealth personally, because he loves to ride 2-strokes and is dedicated to reducing noise levels. The Q-Stealth is living proof FMF is the only exhaust company committed to bringing new technology to the 2-stroke enthusiast.

Titanium Powercore 2.1 All new from the ground up, the FMF Powercore 2.1 silencer is built to provide excellent power for today’s tracks. A smooth power curve throughout the RPM range keeps your 2-stroke motocross bike in the meat of the power! A large diameter canister is designed for more tenability and longer lasting packing life, so you can go longer in-between silencer service.

Turbinecore 2.1

The Q

*Please visit our website for current prices Utilizing a new design inspired by the 4.1 system, the Turbine Core 2.1 utilizes FMF’s exclusive “Turbine Dampening System” to keep noise levels low without sacrificing power. The larger canister extends the life of your silencer packing and delivering a crisp sound that FMF is known for. The straight-through design of the spark arrestor canister and the performance flow stainless steel end cap ensures strength, durability and most importantly, is track and trail proven.

With its longer oval canister, the trademarked Q uses internal technology that retains optimum flow characteristics while enhancing sound absorbtion qualities. The U.S. Forest legal spark arrestor will meet the mandated 96dB sound level set by the US Forest Service making it the quietest 2-stroke performance spark arrestor made! Serious sound deadening qualities and excellent power.

Shorty

Taking the proven success of the Powercore 2, FMF created the Powercore 2 Shorty, with a shorter inner core length and aluminum canister. This design results in a finely tuned bolt on performance silencer that maximizes bottom and mid rpm power. An excellent choice for tight tracks and supercross track applications.
