Stainless Steel Race Header

This specific header, part number 953-204-106, is designed for 2008-2015 Scion xB models. Its advanced CAD-simulated design and flow testing ensure optimal performance and efficiency, while long primary tubes enhance high-RPM power for exhilarating acceleration. The stepped sizing of the header optimizes torque output across a wider RPM range, and the race merge collector provides ample exhaust flow for maximum performance gains. Being catalytic converter-free, this header maximizes power output and reduces back pressure, making it ideal for racing applications, high-performance builds with modifications like camshafts and high-flow intakes, and for drivers who enjoy pushing their engines to their limits. Expect a noticeable boost in horsepower and torque, improved throttle response, a more aggressive exhaust sound, and weight reduction due to its lightweight stainless steel construction. For proper installation and to avoid check engine lights, a CEL Eliminator is recommended. Weapon R offers a Universal CEL Eliminator (Part# 963-111-101) and an Upgraded Adjustable CEL Eliminator (Part# 963-111-104).
