Street Header 4-2-1 Exhaust Header

The Weapon R Street Header is a high-performance 4-2-1 exhaust header engineered to enhance horsepower and torque for 2004-2006 Scion xA and xB models with the 1.5L 1NZFE engine. Constructed from stainless steel with a 4-2-1 design, this header is intended for racing applications. It features a 2.5-inch collector for high exhaust flow and is designed to eliminate the catalytic converter, contributing to better performance gains. The design aims to provide higher torque gains through stepped tubing and is best suited for vehicles with high RPM rev bands. This header is explicitly stated to be for off-road use only and is not street legal. Furthermore, it is not for sale or street use in California and CARB states.
