The FMF MegaBomb Header is a performance exhaust header designed to boost bottom-to-mid power without sacrificing top-end pull. Its MegaBomb chamber helps improve power delivery while also reducing sound output for a more controlled ride.
The FMF MegaBomb Header is built for riders who want a noticeable power boost where it matters most—stronger bottom-to-mid range—while keeping the bike pulling hard on top. Thanks to FMF’s MegaBomb chamber design, it delivers the low-end benefits of a longer header and the rev-happy character of a shorter header, giving you improved rideability across the powerband.
It’s also a smart choice for tracks and riding areas with noise limits. The MegaBomb chamber can reduce sound output by as much as 1.5 dB and pairs well with sound-restricting mufflers, helping you stay compliant without giving up performance.
