RACES Catback exhaust system for Subaru Impreza WRX STI (2002-07)

Upgrading your vehicles exhaust system is a great way to build horsepower, free up trapped torque, and improve upon restrictive factory systems.
The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle. The final result is lower exhaust backpressure, more horsepower, more torque, and a much better sound.
