The 2015 WRX exhaust is extremely quiet in stock form, so we had to create a louder exhaust. We filled this gap with our non-resonated cat-back exhaust. It is mellow, yet aggressive on the 2015-17 WRX, but much louder on the 2011-14 WRX and 2011-17 STI
PERRIN exhaust systems are made entirely of 304 stainless steel. 304SS provides high corrosion resistance and is excellent for heat up to 1800 degrees Fahrenheit. Other manufactures may use cheaper 409 stainless steel which will rust and corrode over time, but the added expense of 304 stainless steel is well worth it for the beautiful, long lasting, high brushed finish and durability.
The PERRIN Dual Tube Cat-back Exhaust is made up of a midpipe, y-pipe, and mufflers. These pieces all connect to one another with exhaust union clamps. These clamps are all long enough to allow for fine adjustments with your exhaust components to get that perfect fitment and get your exhaust tips exactly where you want them.
PERRIN mufflers have a true 3" internal diameter for uninterrupted exhaust flow. PERRIN mufflers and flange connections are 3" throughout the entire length, not necked down, for ultra smooth transitions throughout the system.
Over-sized 3.5" slash cut exhaust tips add an aggressive look to this impressive system. PERRIN exhaust tips sport a more heat-resistant brushed finish compared to the rest of the exhaust system and are of a single wall construction that will not discolor with extreme heat.
Our Y-pipe splitter attaches to the mufflers and midpipe with union clamps which let you adjust muffler location and tip placement to perfectly sit in your bumper cutouts.
Each PERRIN exhaust system comes with a brushed stainless steel finish for corrosion resistance and good looks.
