FMF Racing MegaBomb Header - Details

The science behind the FMF MegaBomb header may be FMF's 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 will have you pulling holeshots and dusting all the boys on the way up Competition Hill. Used by Factory Teams, the MegaBomb is next level technology you can have today. Simply bolt it on and go faster!

  • Stainless steel motorcycle/ATV four-stroke header with FMF's patented MegaBomb module
  • Used by factory teams and is a great compliment to the FMF Factory 4.1 dirt bike or quad muffler
  • Increases output from stock motor as much as 15%
  • Gain up to three horsepower with a single bolt-on mod
  • Produces long header torque and short header over-rev
  • Reduces sound output by as much as 1.5dB

Depending on your year make and model, it is recommended to upgrade. FMF's website has a suggested jet sizing chart based on your bike and your add-ons.
