The 2015 WRX exhaust is extremely quiet in stock form. Our resonated exhaust, although not much louder than stock, still provides 8-10 WHP and a much better sounding exhaust note compared to stock.
3.5" SLASH CUT TIPS
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.
STRAIGHT THROUGH MUFFLER
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.
304SS 3" TUBING
PERRIN Performance exhaust systems are made entirely of 3" Diameter 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.
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.
Our 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.
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
