This optional header provides increased tuning potential when used with the Slip-On Line (Titanium) exhaust. It is constructed using high-grade stainless steel, has a thread for the lambda sensor for those planning to tune the engine electronics, and has no catalytic converter. Power is increased by 1.5 hp at 7,650 rpm, when tested on the Akrapovi? dyno against a Honda CRF300L with a standard stock exhaust. This adds a distinctive deep and sporty sound. It features easy plug-and-play installation, and no remapping is required. This product is meant for racetrack and closed course use only.

THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
