The redesigned PowerBomb is a four-stroke header that incorporates FMFs 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
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)
