      Improved Engine Voice. If you’re not satisfied with your Mustang’s engine tone, but don’t want to go overboard with the volume, you can consider the Cobb Turbo-Back 3-Inch Catted Full Exhaust System for your next mod. The kit comes with COBB-Stamped mufflers, a 10-inch resonator, and a well-balanced Y-pipe that combine to give a deep and louder tone. You won’t exactly wake-up the neighbors with this setup, but it still provides a more exciting ride with hardly any drone noise inside the car on cruise speeds.

      Added Power and Boosted Performance. Beyond sound quality, this full exhaust system unleashes the full power of your Mustang EcoBoost engine. With a better exhaust flow, expect significant horsepower and torque gains on full-throttle.

      Tough Stainless Steel Construction. The Cobb Turbo-Back 3-Inch Catted Full Exhaust System is manufactured in the USA using 304-grade stainless steel to ensure durability and corrosion-resistance. The 3-inch diameter pipes are mandrel-bent to provide a smooth surface for gases to flow enabling a more efficient airflow and reduced back pressure. In addition, the system includes 4-inch polished exhaust tips to give your Mustang a stylish finish.

      Simplified Installation. This exhaust system is compatible with factory and COBB 3-inch downpipes. You’ll be using the factory connection and mounting points for an easy and bolt-on installation. Moreover, all the hardware that you’ll need is included in this complete kit.

      Application. The Cobb Turbo-Back 3-Inch Catted Full Exhaust System fits 2015-2020 Ford Mustang EcoBoost FastBack models without the Active Valve Exhaust.
