Megabomb Header:

FOR CLOSED COURSE COMPETITION USE ONLY. NOT INTENDED FOR STREET USE.

The science behind the Megabomb header may be our greatest engineering accomplishment to date. You can bolt on a Megabomb with an existing FMF Racing slip on for as much as a 3hp boost, plus the Megabomb actually reduces noises levels by as much as 1.5dB. The Megabomb technology is revolved to produce more low end to mid range gains as well as broadening out the mid to top end power gains over stock. The Megabomb is best used for Motocross/Supercross and GNCC style trails. Used by Factory Teams, the Megabomb is the next level technology you can have today.

  • Produces long header torque and short header over-rev
  • Reduces sound output as much as 1.5dB
  • Increases output from stock motor as much as 3hp
  • Made from premium American TiMetal material
  • #1 Header in 2011 Supercross, Motocross, Motocross of Nations and Monster Energy Cup!

Factory 4.1 RCT SL Muffler:

The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology™ both internally and externally. It starts at the center with a new core - a patent pending shape enhances and refines the exhaust pressure wave for optimal power output while lowering the sound level. 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. Visible changes to the exterior include a redesigned canister to increase internal capacity for the maximum volume of packing material. The packing itself was not overlooked – a proprietary blend formulated for superior durability and sound attenuation. The final component is a new rear endcap engineered for simple tuning adjustments incorporating a snap ring feature to secure the standard and optional inserts.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.
