Overview

The Weapon R Stainless Steel Race Header is a high-performance exhaust component designed to increase power and torque.

This header features a 4-2-1 design with long primary tubes for enhanced high-RPM power and stepped tubing for optimized torque across a wider RPM range. It includes a race merge collector for maximum exhaust flow and is designed without a catalytic converter to maximize power output and reduce back pressure.

Ideal for racing applications, high-performance builds, and high-RPM enthusiasts, this header aims to improve throttle response and enhance the exhaust sound. A CEL eliminator is recommended for installation.

Show original supplier description

Designed with advanced computer-aided simulation, these headers feature long primary tubes for enhanced high-RPM power and stepped tubing to optimize torque output across a wider RPM range. The 2.5" race merge collector ensures ample exhaust flow for maximum performance, and the catalytic converter is eliminated to further increase power and reduce back pressure. Ideal for racing applications and high-performance builds, this header is particularly beneficial for vehicles with performance modifications like camshafts and high-flow intakes, as well as for enthusiasts who frequently operate their engines at high RPMs. Users can expect increased horsepower and torque, improved throttle response, and a more aggressive exhaust sound. The construction from lightweight stainless steel also contributes to reduced overall vehicle weight. This header is designed for the 2009-2012 Toyota Corolla (Base, L, LE, S, XLE, XRS) and 2009-2012 Scion xD (Base), all with the 1.8L (1798cc) engine, except for the 2009-2010 Corolla XRS which uses the 2.4L (2362cc) engine. It is important to note that this is a race header and is not for sale or street use in California and CARB states. A CEL (Check Engine Light) Eliminator is recommended and available separately.
