The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology™ both internally and externally. In addition, we achieve a shorter overall length that is less susceptible to crash damage and complementary to our Factory Forward Engineering - moving the muffler closer to the motor to centralize mass. The Factory 4.1 RCT is constructed from only aerospace grade materials that meet our exacting specifications and is manufactured 100% at our Southern California factory.

Megabomb Header

XR 80 XR 80 XR 100

The science behind the Megabomb header may be our greatest engineering accomplishment to date. You can pay an engine builder thousands or bolt on a Megabomb for as much as a 3hp boost! Plus, the megabomb actually reduces noise levels by as much as 1.5dB. The megabomb header will have you pulling holeshots and dusting all the boys on the way up Competition Hill. Simply bolt it on and go faster.

The redesigned PowerBomb is a four-stroke header that incorporates FMF’s patented PowerBomb module at a

precise location in the initial stage of the header. By positioning this “Bomb” at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust sonics through the system. Result is a flow increase of nearly 10%! The outer chamber in the Powerbomb allows the air to expand, cool and ramp back up at a higher velocity. Additionally, the PowerBomb is a “pre-muffler” of sorts which helps to lower the bikes sound output by providing more sound absorbing surface area for the sound medium (exhaust gases).
