The science behind FMF's Titanium MegaBomb header may be their greatest engineering accomplishment to date. You can bolt on a MegaBomb with an existing FMF Racing slip-on for as much as a 3hp boost, plus the MegaBomb actually reduces noises levels by as much as 1.5 dB. FMF MegaBomb technology is specifically designed to produce more low-end to mid-range gains as well as broadening out the mid to top-end power gains when compared to the stock exhaust - a feat unimaginable via conventional header pipe design! The MegaBomb is best used for motocross/supercross riding and GNCC style trails. Used by Factory Teams, the Titanium MegaBomb is the next level technology that you can have today.
