FMF PowerBomb Exhaust Header 12-15 Kawasaki KX 450 F - FMF 042274

The FMF PowerBomb 042274 is a precision-engineered four-stroke header designed to significantly improve exhaust flow and overall engine performance. By integrating FMF’s patented PowerBomb module at a scientifically determined location within the header, this system utilises the expansion and contraction of exhaust sonics to boost flow by almost 10%, resulting in a sharper throttle response and increased power output. The outer chamber also acts as a pre-muffler, reducing noise by enhancing sound absorption as gases pass through. Ideal for competitive riders, the PowerBomb is available in variants tailored for specific power characteristics and retains strict construction quality with durable stainless steel.
