F. GYTR® BY FMF® POWERBOMB® HEAD PIPE 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. This accessory is restricted to closed-course use. Fits ’10—’13 YZ250F 17D-E46A0-S0-00 (Stainless Steel) $199.99
