FMF Racing P-BOMB HEADER XR600 SR650L Headers / Mid Pipes Power Bomb SIL Stainless SteelHONDA XR600 08-00 SX650L093-10 - 040020

The 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 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)
