FMF Header  --------------------------------------------------------------------------

MegaBomb Header

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 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.

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.

 

About FMF ----------------------------------------------------------------------------

Over the decades, FMF seen an amazing transformation in the world of motorcycles and ATVs. The progression of the technology is one of the challenges that keeps FMF going. FMF was there in the days when the single-shock and water-cooled engines were huge innovations and they're glad to be here now for the aluminum chassis and electronic fuel injection. Their goal will never change - take the most advanced machinery to its limit by building the world's best performing exhausts. And its a fact, they build every exhaust by hand from start to finish right here in the U.S.

At the end of the day, there is always one major force keeping them motivated—throwing a leg over the bike and heading for the trails or the track. Their biggest reward for is knowing they're helping customers get the most out of their riding experience. They still ride every chance they get so they never forget why they got into this business in the first place.

History - FMF Racing (Flying Machine Factory) was one of the first aftermarket motorcycle manufacturers, having been started by Don Emler in 1973. From its humble beginnings in Emler's garage, FMF Racing has become 1 of the leaders in manufacturing exhaust pipes, making a number of different pipes for motorcycles and offroad vehicles of all types.
