FMF Racing MegaBomb header pipes will elevate your motorcycle to the next level of technology and power. MegaBomb header uses science to gain up to a 3 hp 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 over stock. FMF Racing MegaBomb header pipes are best for Motocross, Supercross, and GNCC-style trails. Order yours today here at 4WheelOnline.com. Free shipping!
