FMF Megabomb Stainless Steel Header and Mid-Pipe for Husqvarna FE 450 and KTM 450 XCF-W, Part 045644

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 is engineered to deliver broad, usable power gains for off-road and motocross applications. Designed as a performance upgrade for compatible Husqvarna FE 450 and KTM 450 XCF-W motorcycles, this FMF exhaust component can be paired with an existing FMF Racing slip-on muffler to help produce gains of up to 3 horsepower while maintaining strong throttle response.

Megabomb technology is designed to improve low-end and mid-range performance while extending the power curve into the mid- to top-end range. The tuned header design may also reduce exhaust noise by up to 1.5 dB when compared with the applicable stock configuration. Its performance characteristics make it well suited for Motocross, Supercross, and GNCC-style trail riding. Developed with input from factory racing teams, the FMF Megabomb provides a practical way to enhance engine performance without replacing the complete exhaust system.

This stainless steel FMF Megabomb header and mid-pipe is manufacturer part number 045644 and vendor part number 79-0544.
