2.5" Flex Pipe

The Weapon-R 2.5" Flex Pipe is a direct replacement part designed to integrate with exhaust systems, specifically the Weapon-R 4-2-1 Race Headers. Engineered for performance, this flex pipe boasts a 2.5-inch inner diameter and a 6-inch length. The associated Weapon-R 4-2-1 Race Headers are constructed with long primary tubes to optimize high RPM power output, complemented by stepped-size tubing that aims to deliver higher torque gains. A 2.5-inch collector further enhances exhaust flow, contributing to overall performance improvements. This component is specifically intended for all forms of racing and is particularly beneficial for vehicles equipped with performance cams and those that operate within a high RPM range. It's important to note that the catalytic converter is eliminated on all Race Headers when this flex pipe is used as part of the system.
