GNARLY™ PIPES
Power gains are focused toward bottom and mid, with a goal of increased tractability
An excellent off-road pipe, and a winner for tighter tracks
Built with tough 18-gauge steel
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.
