The science behind the MegaBomb header may be FMF's greatest engineering accomplishment to date. You can bolt on a MegaBomb with an existing FMF slip-on for as much as a 3 HP boost, plus the MegaBomb actually reduces noise levels by as much as 1.5 dB...

The science behind the Megabomb header may be our greatest engineering accomplishment to date. You can pay an engine builder thousands or bolt on a Megabomb for as much as a 3hp boost! Plus, the megabomb actually reduces noise levels by as much as 1.5dB...

The FMF Megabomb header is designed with a unique midsection that is comparable to the Powerbomb header giving improved power across the power range. The unique design of the Megabomb Headerpipe allows for better low end torque and also improving top end...
