FMF GasGas 2 Stroke Mufflers
  • The Powercore 2 is the measure which others aim for. With its lightweight extruded aluminum oval canister mated to a perforated core, this silencer is above the competition. The Powercore 2 silencer provides a strong performance edge for any 2-stroke machine and the performance flow end cap and front stinger are stainless steel for unbeatable durability and an unmatched look.
  • 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.
  • The Titanium 2 is our premiere racing silencer. Designed from our commitment to factory level racing and once used by both Yamaha of Troy and Factory KTM, the Titanium 2 is built with a titanium performance flow end cap and titanium stinger to maximize overall weight savings. Combined with an anodized Shorty canister, the Titanium 2 delivers the power characteristics demanded by top riders. Completely rebuildable, the Titanium 2 silencer is the lightest silencer FMF has ever made.
