FMF Megabomb Headers are the ultimate performance upgrade header pipe you'll ever bolt onto your four-stroke dirt bike. The science behind the FMF Megabomb header is perhaps one of FMF's greatest engineering accomplishments yet, and considering the range of impressive products they've constructed throughout their time, that's saying something. You can bolt one of these bad boys on with an existing FMF Muffler and makes gains all the way up to a 3hp boost, which is incredible! Plus, the Megabomb Header pipe can actually reduce noise levels by as much as 1.5dB, so it's a win-win situation all around. The technology behind the Megabomb works to produce a higher low end to mid-range power gains, as well as broadening the mid to top-end power of your stock exhaust header.
