PowerBomb Exhaust Header 99-14 Honda TRX 400 EX X - FMF 040014

FMF Racing’s PowerBomb 040014 is a high-performance four-stroke header, engineered to enhance exhaust flow and deliver notable horsepower gains. Utilising FMF’s patented PowerBomb module strategically integrated into the initial section of the header, this system increases exhaust flow by almost 10% through the controlled expansion and contraction of exhaust pressure waves. The result is not only improved throttle response and increased velocity, but also a reduction in sound output thanks to the “pre-muffler” effect, making it ideal for closed course applications. Constructed from durable stainless steel, the PowerBomb 040014 header combines performance gains with robust build quality for demanding off-road conditions.
