PowerBomb Exhaust Header 07-15 Yamaha 450 WR YZ F - FMF 044225

The FMF PowerBomb 044225 is a performance four-stroke header engineered with FMF’s patented PowerBomb module strategically positioned in the initial stage of the exhaust system. This advanced design increases exhaust flow by nearly 10% by utilising sonic expansion and contraction within the outer chamber, significantly improving horsepower and velocity. The PowerBomb also acts as a pre-muffler, helping to reduce overall sound output by expanding the exhaust gases and increasing sound-absorbing surface area. Available in stainless steel construction, it is ideal for riders seeking a substantial boost in performance and throttle response.
