Perrin's new catback exhaust system for the new 2008 STi continues their line of high quality performance driven exhaust products. This new system was designed specifically with the new STi hatchback body style in mind, ensuring the least amount of bends and the highest flow possible without compromising sound quality or performance. The Perrin Performance catback exhaust systems for the 2008-2009 STi feature full 304 stainless steel construction, V-band piping connections (no more gaskets or bolts!) and 3.5-inch quad tips.
You can also expect an extremely sporty signature Subaru exhaust note with virtually no drone! The advantages don't stop there, Perrin has observed performance gains of 8-10 horsepower and torque throughout the powerband with one of these units on an otherwise bone stock 2008 STi.
The Perrin exhaust kit for the 08-09 STi is a full catback exhaust system consisting of a center-pipe, mid-pipe, and axleback exhaust sections and includes all V-band clamps, hardware and instructions for a tidy and timely installation experience. Rest assured you are getting one of the highest quality, best sounding, best looking and top performing exhaust systems on the market with this kit from Perrin Performance. Perrin also offers the mid and muffler pipes separately for a stealthier system and are flanged to fit seamlessly with your stock exhaust components.
