Enhance your Yamaha YZ250F or WR250F with the FMF Racing Power Bomb Header System designed specifically for models from 2003 to 2006. This high-performance 4-stroke header features FMF's patented Power Bomb module strategically placed in the initial stage of the header. By positioning the Power Bomb at this critical point, the system increases exhaust flow efficiency by nearly 10%, resulting in improved throttle response and overall engine performance. The perforated core surface allows sound waves to escape into the absorbing material, which helps reduce noise levels while maintaining optimal exhaust flow. This design acts as a pre-muffler, providing additional sound dampening and contributing to quieter operation without sacrificing power. Built with durable materials and engineered for precise fitment, this header system ensures seamless installation and long-lasting performance. The system is compliant with EPA standards and ready to install on your Yamaha motocross or off-road bike, making it an ideal upgrade for competitive riders and enthusiasts seeking enhanced power and sound management.
