Titanium MegaBomb Exhaust Header 25-26 Honda CRF 250 R RX - FMF 041615

The FMF Racing Titanium MegaBomb header is a single-header exhaust component for the listed Honda CRF250R and CRF250RX models. Designed for closed-course motocross and off-road use, it incorporates a MegaBomb expansion chamber to support low-to-midrange response and broaden power delivery towards the top end.

Features

• For closed-course use only.


• MegaBomb design is intended to improve throttle response and reduce exhaust sound output.


• Designed to pair with a compatible FMF slip-on silencer; FMF does not recommend or guarantee fitment with a standard silencer.
