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.
Upgrade your Yamaha dirt bike with the FMF Racing Yamaha YZ250F, YZ450F, WR250F exhaust header system, part number 044232. This high-performance 4-stroke header integrates FMF's patented Power Bomb module at a precise location within the initial stage of the header. This strategic placement allows for a nearly 10% increase in exhaust flow by optimizing the expansion and contraction of exhaust gases, resulting in improved power delivery across your bike's RPM range. Crafted with a perforated core, the system directs sound into absorbing material, effectively reducing noise levels while maintaining optimal exhaust flow. The Power Bomb acts as a pre-muffler, providing additional sound-absorbing surface area that helps to lower overall sound output, making it ideal for riders seeking increased performance without excessive noise. Made from durable materials, this header system is designed for reliability and long-lasting use under demanding riding conditions. It is compliant with EPA standards, ensuring environmentally responsible performance without sacrificing horsepower gains. The system is compatible with multiple Yamaha models from 2006 to 2013, including the YZ250F, YZ450F, and WR250F, making it a versatile upgrade for enthusiasts looking to enhance their bike's exhaust efficiency and sound profile. Easy to install, this component is a perfect choice for riders aiming to improve their motorcycle's performance, sound, and overall exhaust flow.
