Subaru WRX/STI Cat Back Exhaust, Polished Quad 3.5" Tips

CORSA's catback exhaust systems for the 2015 Subaru WRX and STI feature 3" stainless steel mandrel bent piping and dual exit configuration with twin polished or black 3.5" tips. These catback systems are categorized with CORSA's "Sport" sound level which produces a deep growl at idle and screams in the high RPM's but creates no drone during cruising thanks to CORSA's RSC Technology.

Patented RSC Technology allows CORSA to acoustically style the sound of your vehicle to give you the true voice of performance without the annoying drone while cruising. Straight through nonrestrictive system design maximizes airflow improving performance and fuel economy. All components; even clamps and hangers; of the system are constructed of premium grade stainless steel to ensure the look and sound of your CORSA system that won't change over the life of your vehicle. Proudly designed and manufactured in Berea OH USA. Quickly enjoy the CORSA sound with an easy bolt on installation. No welding needed and all hardware and detailed instructions are included. Limited LIFETIME warranty for as long as you own your vehicle.

Aggressive Performance Sound

Corsa Exhaust systems are all acoustically styled and engineered to match the make, model, and harmonics specific to your vehicle. Each system is designed to match the personality of a car and its owner.

No Drone

This is what sets Corsa apart from other exhaust manufacturers: RSC technology eliminates "problem" frequencies that cause interior drone/resonance at cruising speeds. You can add CORSA and enjoy your car at idle, on acceleration and while cruising down the road.

Improved Horsepower And Torque

Patented non-restrictive Straight-through design reduces back pressure and frees up additional power.

Potential For Better Fuel Economy

Less back pressure and more power means your engine functions more efficiently and that translates into better fuel economy.

Premium 304L Stainless Steel Construction

The combination of 304L stainless steel construction and the fact that their systems don't use cheap easily degraded packing materials ensure your product will last.

Limited Lifetime Manufacturer Warranty

The combination of 304L stainless steel construction and the fact that their systems don't use cheap easily degraded packing materials ensure your product will last.

Excellent quality

Purchased this exhaust for the quality and one of a kind sound it produces. Comes with everything you need if you're installing with an upgraded 3 inch down pipe. If you have a stock down pipe you will need to get an adapter.

Great Exhaust & Great Service from MAP

I have been listening to various exhaust sound on youtube, finally pull the trigger on Corsa Exhaust. I placed order with MAP on Sunday the shipment arrived Wednesday (Very Fast, Thank you MAP Team). Got it installed today, love it so much. The sounding is very precise, not as loud, the sound come only when you are on the throttle.

Thank you again MAP Team for fast shipment and customer support

Great Exhaust

So after shopping around I finally decided to purchase the corsa cat back and let me tell you I don't regret it at all. The MAPerformance team is one of, if not the best place to buy from. I ordered my exhaust and 2 days later it arrived, installation is straight forward and everything is provided.

Once the exhaust was mounted up it seems a little quite at first, but after it was broken in a few days later it had a nice low rumble tone and little to no drone at all. The car does feel like it has open up a lil more and I can't wait to do the J-pipe and intermediate pipe and really hear the exhaust and open the car up more.
