  • 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).
  • 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
