FMF PowerBomb Header for Yamaha YFZ450 and YZ450F Models

The FMF Power Bomb is a four stroke header pipe unit that has a unique bulge precisely located in the header system. A "pre muffler" of sorts, the Power Bomb actually lowers sound output because it creates more surface area to absorb the sound medium (exhaust). The surface area 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 with the higher pressure air. The result? The FMF Power Bomb is instrumental in reducing the decibel level on any four stroke and because of the expansion and contraction on exhaust through the system, the flow has been increased by nearly 10%. That means more power throughout the range.

The FMF PowerBomb header pipe is a high-performance component designed specifically for four-stroke off-road motorcycles, including Yamaha YFZ450 and YZ450F models from 2003 to 2013. This header features a unique bulge strategically located in the header system, functioning as a pre-muffler that significantly reduces sound output by increasing surface area and absorbing exhaust noise through steel wool packing. This design not only minimizes decibel levels but also enhances exhaust flow, leading to an approximate 10% increase in power across the engine's range. Built with precision, the PowerBomb header optimizes bottom to mid-range performance, making it ideal for riders seeking improved responsiveness and quieter operation without sacrificing power. Its construction ensures full service access to the oil filter, facilitating maintenance and longevity of the motorcycle’s engine. The header is compatible with various Yamaha models, offering a reliable upgrade for off-road enthusiasts looking to boost their vehicle’s performance and reduce noise levels. This header is part of FMF's renowned lineup of headers, Y-pipes, and manifolds, trusted for quality and durability in demanding off-road conditions. Whether you're trail riding or participating in competitive events, the FMF PowerBomb header provides a performance edge while maintaining a quieter, more manageable exhaust note, ensuring your bike performs efficiently and sounds great. Installation is straightforward, and its durable build ensures long-lasting performance in rugged off-road environments.
