The 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 Moto Version Focuses on the Mid to Upper RPM Range. 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).
