FMF Stainless Steel SX PowerBomb Header

The redesigned SX 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 waves as they pass through the system. The result is a flow increase of nearly 10% in the lower to middle RPM ranges which is perfect jumping off corners at tighter track!

The outer chamber in the Supercross PowerBomb allows the air to expand, cool and ramp back up at a higher velocity as it passes through this section. Additionally, the PowerBomb also acts as a pre-muffler of sorts which helps to lower the bike's sound output by providing more sound absorbing surface area within the exhaust.
