FMF Racing MegaBomb Header pipes deliver your motorcycle to the next level of technology and power. MegaBomb uses science to gain up to a 3hp boost with an existing FMF Racing slip while reducing noise levels by as much as 1.5 dB. Bolt them on, and the technology produces more low-end to midrange gains, as well as broadening out the mid to top-end power gains overstock. FMF Racing MegaBomb header pipes are best for Motocross, Supercross, and GNCC-style trails.
