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 bike's sound output by providing more sound absorbing surface area for the sound medium (exhaust gases). On some models, choices can be 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.
- Increased performance and flow through the system.
- Allows the air to expand, cool and ramp back up at a higher velocity.
- Helps lower the sound output by providing more sound absorbing surface area for the sound medium.
