FMF PowerBomb Header

The redesigned PowerBomb is a four-stroke header incorporating FMF's patented PowerBomb module at a precise point near the beginning of the pipe. Positioning this chamber at a key point improves performance and flow through exhaust-gas expansion and contraction, increasing flow by nearly 10%.

The outer chamber allows the gases to expand, cool and regain speed. The PowerBomb also acts as a pre-muffler, helping reduce noise by providing more sound-absorbing surface area for the exhaust gases.

Some models offer a motocross or supercross version. The supercross version targets low-to-mid-range power; the motocross version focuses on mid-to-high rpm.
