PERRIN Dual Catback Exhaust - 2011+ WRX & STI Sedans




The PERRIN Dual Catback Exhaust is designed for high performance, long life, and great sound. Splitting the exhaust flow into two tubes creates a higher flow capacity and a unique sound for your Subaru boxer engine. 


It is very important for aftermarket exhaust systems to sound great and the PERRIN Dual Tube Catback Exhaust sounds awesome. Wake up that quiet WRX or STI and give it that Subaru rumble with a unique PERRIN tone; nothing else is quite like it!

Dual tube Design

The PERRIN Dual Tube Catback Exhaust is unique in a world full of bland 3 exhaust systems. The system starts out as a single 3 tube and transitions into a y that feeds into dual 2.25 tubes. These two 2.25 tube continue all the way out to the mufflers at the back of the car.

Performance and Flow

Dual 2.25 tubes flow more than the typical 3 tube while producing lower sound levels. Dual 2.25 tubes have 12.5% more internal volume than a single 3 tube for increased flow capacity that can handle the power you want to put through it.

304 Stainless Steel Tubing

304ss provide high corrosion resistance and is excellent for heat up to 1800 degrees Fahrenheit. Other manufactures may use a cheaper 409 stainless steel which will rust and corrode over time but the added expense for 304 stainless steel is well worth the beautiful and long lasting finish and durability.
