The science behind the Megabomb header may be our greatest engineering accomplishment to date. You can bolt on a Megabomb for as much as a 3hp boost, plus the Megabomb actually reduces noises levels by as much as 1.5dB. Used by Factory Teams, the Megabomb is the next level technology you can have today.  Produces long header torque and short header over-rev Reduces sound output as much as 1.5dB Increases output from stock motor as much as 3hp Made from premium American TiMetal material
