Fits: 2004-2012 Honda CRF450X CRF450R 2004-2008The 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 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 r 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). Designed for use with FMF mufflers and not guaranteed to fit other brands of mufflers.Payment We AcceptAbout In-store PickupFor instore pick-ups, you will be notified via phone and email when your items are ready for pick-up.
