The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology both internally and externally. In addition, it achieves a shorter overall length that is less susceptible to crash damage and complementary to FMF's 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 FMF's exacting specifications and is manufactured 100% at their Southern California factory.

  • Made from anodized blue titanium with a carbon fiber end cap and a titanium mid-pipe and PowerBomb header
  • Massive power gains throughout the RPM range
  • Huge weight savings
  • New RTS (Rapid Tuning System)
  • Spark arrestor and 94dB quiet insert included

FMF PowerBomb Header:

  • Titanium 4-stroke ATV 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 the flow increases nearly 10%
  • The ducted core allows the exhaust gases to exit into the Bomb chamber, expand, cool and ramp back up at a higher velocity
  • Acts as a 'pre-muffler' to lower the quad's sound output by as much as 1.5dB through providing more sound absorbing surface area for the sound medium (exhaust gases)
  • Proven PowerBomb patented technology provides increased performance of up to 10% horsepower gain
  • Only available from FMF Racing, don't be fooled by knock-offs
  • The most copied header in the world
