Show original supplier description
Its advanced design utilizes computer-aided simulation and flow testing to ensure optimal efficiency and output. Key features of this race header include long primary tubes, which are crucial for enhancing high-RPM power and providing exhilarating acceleration. Furthermore, the race merge collector facilitates ample exhaust flow, contributing to maximum performance gains. Designed as a catalytic converter-free component, it aims to maximize power output and minimize exhaust back pressure for a more aggressive performance profile. This header is ideal for racing applications such as drag racing and road racing, as well as high-performance builds that may include modifications like camshafts and high-flow intakes. It is also suited for high-RPM enthusiasts who enjoy pushing their engines to their limits, offering improved throttle response and a more aggressive exhaust sound. It is important to note that this race header is not for sale or street use in California and CARB states. Additionally, a Check Engine Light (CEL) Eliminator is recommended for this header, with Universal (Part# 963-111-101) and Upgraded Adjustable (Part# 963-111-104) options available.
