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 evolved to produce more low end to mid range gains as well as broadening out the mid to top end power gains over stock. MegaBomb is the next level technology you can have today.
For FMF mufflers only
The FMF Powerbomb is a four stroke header pipe unit that has a unique bulge precisely located in the header system. A "pre-muffler" of sorts, the Power Bomb actually lowers sound output because it creates more surface area to absorb the sound medium (exhaust). The surface area of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up with the higher pressure air. The result? The FMF Powerbomb is instrumental in reducing the decibel level on any four stroke and because of the expansion and contraction on exhaust through the system, the flow has been increased by nearly 10%. That means more power throughout the range.
