The 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
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)
