Offering an impressive increase in power of over 10% and a huge weight savings of 48% over the stock item, the 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 13.6% at 8,600 rpm, with torque increased by 14.7% at 8,700 rpm when tested on the Akrapovic dyno against a Honda MSX 125 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 exhaust is meant for racetrack and closed course use only. THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
