Perrin Quad Tip Non-Resonated Brushed Cat Back Exhaust - 11-16 Subaru WRX / STI
PERRIN Performance catback exhaust for your 2008-2013 STI hatchback and 2011-2013 WRX hatchback is one of the best and first modifications you should do to your Subaru, gain horsepower and unleash that aggressive Subaru sound. Made from 3" 304ss tubing for maximum exhaust flow and extreme durability. The PERRIN Performance catback exhaust features a direct bolt on installation to the OEM down pipe and aftermarket down pipes with no "neck down" because of a special flange that is designed to bolt to both the smaller OEM flange and the larger aftermarket flanges. This is followed by an intermediate V-band connection that allows fine tuning of the exhaust alignment and provides an air tight seal and finally a flat flange at the OEM axel back position.
Finishing off the PERRIN catback is a true 3" inside diameter muffler and four 3.5" slash cut tips, two on each side.
