Show original supplier description
Elevate your vehicle's performance with Weapon R's Stainless Steel Race Headers. Key features include advanced CAD simulation and flow testing for optimal performance, long primary tubes that enhance high-RPM power, and stepped sizing to optimize torque across a wider RPM range. The race merge collector ensures ample exhaust flow for maximum performance gains, while the catalytic converter-free design maximizes power output and reduces back pressure. This header is constructed from lightweight stainless steel, contributing to weight reduction and potentially improved handling. It aims to provide increased horsepower and torque, improved throttle response for quicker acceleration, and an enhanced, more aggressive exhaust sound. Installation of this header may trigger a Check Engine Light (CEL). It is recommended to use a Universal CEL Eliminator (Part# 963-111-101) or an Upgraded Adjustable CEL Eliminator (Part# 963-111-104). While dyno charts for a 2016 Scion TC and a 2010 Toyota Yaris are referenced, direct fitment information for this specific header is primarily for 1992-1998 Honda Civic SOHC models. It is noted that this product may not have extensive fitment applications beyond the specified models.
