OVERVIEW

 

The PERRIN Catback Exhaust for 2002-2007 WRX & STI features an all stainless steel design, a straight through muffler and a 4” slash cut tip.  This adds 15 WHP and brings out the sought after boxer rumble.

 

15 HORSEPOWER

 

This test was done on an 2007 STI running a stock ECU tune. We swapped out the exhaust in five minutes and re-dynoed the car to find an additional 15WHP and 15ft-lbs of torque.
