32:T4a4,FMF PowerBomb Header The FMF PowerBomb Header is engineered for riders who spend most of their time in the mid to upper RPM range and want stronger, more efficient power delivery. Developed by FMF Racing, the PowerBomb uses a patented expansion chamber strategically placed in the initial stage of the header to optimize exhaust flow. This unique chamber allows exhaust gases to expand and then contract, resulting in nearly a 10% increase in flow compared to a standard header. The outcome is improved mid-to-top end power that’s more usable and responsive, especially under aggressive riding conditions. In addition to performance gains, the PowerBomb also functions as a pre-muffler, helping reduce overall exhaust sound output without sacrificing power.
