Overview

The Perrin Performance cat-back exhaust is a quad-tip exhaust system designed for 2008-2012 Subaru STI hatchbacks and 2011-2012 Subaru WRX hatchbacks. This system features a 3-inch inlet pipe that splits into dual 2.25-inch pipes to feed four 3.5-inch slash-cut stainless steel tips.
Show original supplier description
It is explicitly designed for the 2008-2012 Subaru STI hatchback and 11-12 Subaru WRX hatchback. The system utilizes high-tech v-band clamps, which eliminate the need for gaskets while allowing for precise joint rotation during installation, ensuring both easy alignment and a durable, pressure-resistant connection. Constructed entirely from 304 stainless steel, this exhaust provides high corrosion resistance and thermal tolerance up to 1800 degrees. The design centers on a 3-inch inlet pipe that transitions into a distribution chamber, feeding two 2.25-inch pipes that terminate in four 3.5-inch polished slash-cut tips. This configuration is specifically tuned to provide a mellow, pleasing exhaust note that avoids excessive volume. Installation requires basic mechanical tools, and users should follow torque specifications for v-band clamps to ensure a secure, leak-free joint. Each system ships with necessary hardware, a midpipe, the muffler section, and a lifetime warranty for the original purchaser.
