- FOR CLOSED COURSE COMPETITION USE ONLY. NOT INTENDED FOR STREET USE.
- 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
