    Subaru WRX/STI Cat Back Exhaust, Black 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.

    Included All Necessary Hardware And Full Color Instructions

    Corsa Exhaust systems come with top quality TORCA Clamps, that are also 304SS, and instructions that feature actual full color photos to make your install as simple as possible.

    50 State Emissions Legal

    Since their systems are all designed to install rearward of the factory catalytic converter there are no emissions hassles. Just bolt it on and go.

    Handcrafted In The USA

    Every system is proudly manufactured in Berea, OH, USA.
