Perrin - Subaru 11-21 STi/WRX - Dual Tube Cat-Back Exhaust w/ Quad Straight Cut Tips (Brushed Stainless Steel)
The PERRIN Dual Tube 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" tubes continues 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 CONSTRUCTION
The PERRIN Dual Tube Catback Exhaust is made entirely of 304 stainless steel. 304SS provides high corrosion resistance and is excellent for heat up to 1800 degrees Fahrenheit.
Other manufacturers may use cheaper 409SS, which will rust and corrode over time, but the added expense of 304SS is well worth it for a beautiful, long-lasting finish.
The PERRIN Dual Tube Catback Exhaust has a brushed finish for sporty good looks that will last the lifetime of your car.
Extra attention is paid to the tips as they are what you see once the exhaust is installed. Extra precise brushed finish with an etched PERRIN logo and straight cut 3.5" diameter tips really stand out with a motorsports look.
