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 MegaBomb header may be the best kept holeshot secret. Used by Factory Teams, the MegaBomb is next level technology you can have today. Simply bolt it on and go faster.

POWERBOMB

The PowerBomb header increases horsepower as much as 10% due to it’s patented design. The ducted core allows the exhaust gases to exit into the Bomb chamber, expand, cool and ramp back up at a higher velocity resulting in increased flow. As an added benefit, the PowerBomb acts as a ‘pre-muffler’ to lower the sound output. Don’t be fooled by knock-offs. The PowerBomb header is proven technology and only available from FMF Racing.
