FMF Power Bomb Moto SS YZ450F Header 03-13 for Yamaha YFZ450 and YZ450F

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 Power Bomb Moto SS YZ450F Header (Part Number: 044033) is a performance-enhancing exhaust header designed specifically for Yamaha YFZ450 and YZ450F models from 2003 to 2013. Its unique bulge in the header system acts as a pre-muffler, effectively reducing sound output while increasing exhaust flow. The perforated core surface area absorbs sound waves, decreasing decibel levels, which makes it ideal for riders seeking quieter operation without sacrificing performance. Through this innovative design, the Power Bomb enhances sound absorption and provides a smoother, more refined exhaust note. Additionally, the expansion and contraction of exhaust gases within the system improve flow efficiency, increasing power output by nearly 10% across the entire RPM range. This upgrade is suitable for riders who want a noticeable boost in bottom to mid-range performance, while also benefiting from a quieter ride. The header features full service access to the oil filter, simplifying maintenance tasks and ensuring ease of installation. Built with durability in mind, the FMF Power Bomb Moto SS header is constructed with high-quality materials to withstand the rigors of off-road riding and aggressive use. Whether upgrading for improved performance or sound management, this header offers a balanced solution for Yamaha ATV and dirt bike enthusiasts seeking reliable and effective exhaust enhancements.
