The Stainless Steel PowerBomb™ is a four-stroke header that incorporates the 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. 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). The PowerBomb™ provides power focused in the mid to upper rpm range.
