FMF MegaBomb Header Kawasaki KX450F

The science behind the FMF Megabomb header may be FMF's 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 designed to produce more low end to mid range gains as well as broadening out the mid to top end power gains over stock. The FMF Megabomb is best used for Motocross/Supercross and GNCC style trails. Used by multiple Factory Teams, the Megabomb Header delivers next level technology you can have today.

Features:

Less susceptible to crash damage than longer headers
Produces long header torque and short header over-rev
Reduces sound output as much as 1.5 dB
Increases output from stock motor as much as 3 hp
Compatible with FMF muffler
100% made in the USA

Weight:

Stainless Steel 1.8 lbs
Titanium 1.1 lbs
