Upgrade your bike’s power delivery with the FMF MegaBomb header pipe, engineered to improve bottom-to-mid range performance without sacrificing top-end. Its durable construction is less susceptible to damage than a long header and works well with sound-restricting mufflers.
The FMF MegaBomb Header Pipe is built for riders who want a noticeable boost in usable power where it matters most—coming out of corners and through the mid-range—while still keeping strong pull on top. The MegaBomb design is tuned to deliver the low-end characteristics of a longer header together with the top-end benefits of a shorter header, giving you a broader, more rideable powerband.
Beyond performance, this header is designed with real-world riding in mind. Compared to a long header, it’s less susceptible to damage—an advantage for aggressive motocross and off-road use. It also pairs well with sound-restricting mufflers and can help effectively reduce sound output by up to 1.5 dB depending on your overall exhaust setup (note: it will not pass the 2025 FIM sound regulation).
