The FMF Racing PowerBomb 045286 is a high-performance four-stroke header engineered to deliver a significant increase in exhaust flow and power output, utilising FMF's innovative PowerBomb module. Strategically placed within the initial stage of the header, the chamber expands and contracts exhaust sonics, increasing flow by nearly 10%. This "pre-muffler" design also contributes to a reduction in sound output, offering both performance gains and a quieter ride. Constructed from durable stainless steel, it is an optimal upgrade for riders seeking maximum throttle response in demanding ATV applications.
