FMF Racing 25+ Kawasaki KX250F Hex Q4 S/A Muffler

A 4-Stroke header system that incorporates FMF's patented Power Bomb module at a precise location in the initial stage of the header system; by positioning the "Bomb" at this key point, the expansion and contraction of exhaust sonics through the system resulting in a flow increase of nearly 10%. The surface of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up at higher air pressures (RPMs). The Power Bomb is a "pre-muffler" of sorts, which helps to lower the bike's sound output because it provides more sound-absorbing surface area to allow the exhaust gases to become absorbed.

The FMF Racing Power Bomb Header System for the 2025 Kawasaki KX250F is engineered to optimize your motorcycle’s exhaust performance with precision. Featuring FMF's patented Power Bomb module strategically positioned in the initial stage, this header enhances exhaust flow by nearly 10%, resulting in improved throttle response and power delivery. Constructed with durable materials, the system ensures long-lasting performance under demanding riding conditions. The perforated core design allows sound waves to exit into the absorbing steel wool packing, which helps reduce noise levels while maintaining optimal exhaust efficiency. This design effectively acts as a pre-muffler, providing additional sound dampening and a cleaner exhaust note without sacrificing performance. The header system integrates seamlessly with your bike, offering a straightforward upgrade to enhance both sound quality and exhaust flow, making it suitable for trail riding, motocross, or competitive events. Easy to install and built to meet high-performance standards, this system is an excellent choice for riders seeking increased power and a quieter ride from their Kawasaki KX250F.
