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 WRX, but much louder on the 2011-2014 WRX and 2011-2015 STI.
Over-sized 3.5" slash cut exhaust tips add an aggressive look to this impressive system. PERRIN exhaust tips sport a higher brushed finish compared to the rest of the exhaust system and are of a single wall construction that will not discolor with extreme heat.
PERRIN Performance 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.
PERRIN Performance exhaust systems are made entirely of 3" Diameter 304 stainless steel, inside and out. 304SS provides high corrosion resistance and is excellent for extreme heat up to 1800 degrees Fahrenheit. Other manufactures and OEM parts 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 as well as for durability.
PERRIN Performance exhaust systems feature high tech v-band clamps for a perfect exhaust connection. V-band clamps are designed to hold hundreds of pounds of pressure and do so without the need for a gasket! This connection allows for a precise and repeatable joint with the ability to rotate each joining connection. This allows for easy installation and alignment adjustments for a perfect fit every time.
Their Y-pipe splitter features two slip joints which let you adjust muffler location and tip placement to perfectly sit in your bumper cutouts.
The PERRIN exhaust system comes with a brushed stainless steel finish. The slash cut exhaust tips are a higher brushed aluminum.
PERRIN Performance warrants to the original purchaser, all PERRIN cat-back exhaust systems to be free from defects in material and workmanship. *Some exclusions apply.
