PowerBomb Exhaust Header 08-09 Kawasaki KLX 450 R - FMF 042131

The FMF Racing PowerBomb 042131 is a four-stroke header engineered to maximise performance by incorporating FMF’s patented PowerBomb module at a precise location within the header. This unique design increases overall exhaust flow by nearly 10%, enhancing both horsepower and throttle response. The external PowerBomb chamber creates an environment where exhaust gases expand, cool, and accelerate, promoting superior exhaust flow characteristics. Furthermore, the system functions as a pre-muffler, effectively reducing noise output by providing additional internal sound absorption. The PowerBomb 042131 is crafted from durable stainless steel, ensuring both longevity and consistent performance.
