FMF Power Bomb Stainless Steel HeaderThe redesigned PowerBomb is a four-stroke header that incorporates FMFs 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. 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 bikes 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 in the mid to upper RPM range.FMF Model # 041082Fitment:2005-2009 Honda CRF450X2004-2008 Honda CRF450R*Note: Actual product may slightly vary depending on make and model.
