FMF Headers |

MegaBomb Stainless Steel | |
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.

PowerBomb Stainless Steel Headers | |
The redesigned PowerBomb is a four-stroke header that incorporates FMF's patented PowerBomb module at a precise location in the initial stage of the header. By positioning this "Bomb" at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust sonics through the system. Result is a flow increase of nearly 10%! The outer chamber in the PowerBomb allows the air to expand, cool and ramp back up at a higher velocity. Additionally, the PowerBomb is a "pre-muffler" of sorts which helps to lower the bikes sound output by providing more sound absorbing surface area for the sound medium (exhaust gases). On some models, you can choose between a moto or supercross version. The supercross version is designed for more low to mid-range power where the moto version is focused in the mid to upper RPM range. |
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. |
