END OF LINE PowerBomb Exhaust Header 11-12 KTM 250 SX-F XC-F - FMF 045420
The redesigned PowerBomb is a four-stroke header that incorporates FMF’s patented PowerBomb module at a precise location in the initial stage of the header. By positioning this "Bomb" at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust sonics through the system, resulting in a nearly 10% flow increase. The outer chamber in the Powerbomb allows the air to expand, cool and ramp back up at a higher velocity. The PowerBomb also acts as a "pre-muffler," lowering the bike's sound output by providing more sound absorbing surface area for the exhaust gases. This header is constructed of titanium and fits FMF silencers only. Weight is 1.2 lbs. For Closed Course Use Only. Manufacturer part number 045420.

FULL DESCRIPTION
FMF PowerBomb Exhaust Header
The FMF PowerBomb Header is a performance-enhancing exhaust component designed to optimize your motorcycle's exhaust system. This header integrates FMF's patented PowerBomb module, strategically placed to manage exhaust sonics through expansion and contraction. This design results in a significant increase in flow, up to 10%, and provides a noticeable performance boost.
The unique outer chamber of the PowerBomb allows exhaust gases to expand and cool, then rebound at a higher velocity. This "pre-muffler" effect also contributes to a reduction in sound output by increasing the surface area available for sound absorption.
