FMF PowerBomb Header For Honda CRF230L CRF230M Stainless Steel 041480

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. 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 bike's sound output by providing more sound absorbing surface area for the sound medium (exhaust gases).
