PowerBomb Exhaust Header 07-09 Yamaha YZ 250 F - FMF 044244

The FMF Racing PowerBomb 044244 is a high-performance four-stroke header engineered to maximise your motorcycle’s exhaust flow and power output. Featuring FMF’s patented PowerBomb module, strategically integrated at a critical location in the header, it delivers a nearly 10% increase in exhaust flow by enabling exhaust gases to expand, cool, and accelerate, leading to enhanced throttle response and overall performance. The unique chamber design also reduces overall sound levels, serving as a “pre-muffler” for greater sound absorption. Purpose-built for closed course use, the PowerBomb is the ultimate choice for riders seeking both competitive edge and refined power delivery.
