FMF Racing PowerBomb Header:

  • Stainless steel four-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
