FMF Stainless Steel MX PowerBomb Header

The redesigned Moto 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% at middle to upper RPM ranges which is perfect for outdoor moto riding!

The outer chamber in the 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.
