FMF Megabomb Stainless Steel Header and Mid-Pipe 045659 for KTM 450/500 EXC-F and Husqvarna FE 450/501

The science behind the Megabomb header may be our 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.

The FMF Megabomb Stainless Steel Header and Mid-Pipe, manufacturer part number 045659 and vendor part number 045659, is engineered to improve exhaust performance across the powerband. Designed for select KTM and Husqvarna four-stroke enduro motorcycles, this Megabomb header works with an existing FMF Racing slip-on muffler and can deliver gains of up to 3 horsepower when properly matched.

Megabomb technology is designed to increase low-end and mid-range performance while extending mid-to-top-end power beyond the stock exhaust configuration. The header also helps reduce exhaust noise by as much as 1.5 dB, providing a performance-focused upgrade for motocross, Supercross, and GNCC-style trail riding. Its stainless steel construction is built for demanding off-road use, and its proven design is used by factory racing teams.
