Perrin PSP-EXT-351BR Cat-Back Dual Tube Exhaust (WRX/STi 11-20)

MATERIAL AND FINISH

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.

EXHAUST UNION CLAMPS

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.

STRAIGHT THROUGH MUFFLER

PERRIN mufflers have a true 3" internal diameter for uninterrupted exhaust flow. PERRIN mufflers and Y-pipe connections are 3" throughout the entire length, not necked down, for ultra smooth transitions throughout the system.

3.5" STRAIGHT CUT TIPS

Over-sized 3.5" straight 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.

ADJUSTABLE Y-PIPE

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.

FINISH

Each PERRIN exhaust system comes with a brushed stainless steel finish for corrosion resistance and good looks.
