FMF - ATV 4-Stroke Powerbomb Header
  • 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, the 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)
  • On some models, you can choose between a moto or supercross version
  • The supercross version is designed for more low to mid-range power where the moto version is focused in the mid to upper RPM range
