The new Perrin Catback exhaust for the Subaru WRX and STI results from a long while of R&D. This new system achieves a 15whp gain and well as a killer look sure to make your car shine. 3in plumbing is used all the way through this system for maximum air flow and the center section is resonated to prevent highway drone. Perrin also offers the mid and muffler pipes separately for a stealthier system and are flanged to fit seamlessly with your stock exhaust components.
