FMF Megabomb Header with Mid Pipe for Yamaha YZ450F and YZ450FX - Offroad Exhaust Solution

The science behind the Megabomb header may be our 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 1.5dB. The Megabomb technology is revolved to produce more low end to mid range gains as well as broadening out the mid to top end power gains over stock. The Megabomb is best used for Motocross/Supercross and GNCC style trails. Used by Factory Teams, the Megabomb is the next level technology you can have today.
