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 are achieved through the expansion and contraction of exhaust sonics through the system. The result is a flow increase of nearly 10%! The outer chamber in the Powerbomb allows the air to expand, cool, and ramp back up at a higher velocity. Additionally, the PowerBomb is a “pre-muffler” of sorts which helps to lower the bike's sound output by providing more sound-absorbing surface area for the sound medium (exhaust gases). On some models, you can choose between a moto or supercross version. The supercross version is designed for more low to mid-range power where the moto version is focused on the mid to upper RPM range.
