      Increases Power and Performance. The Roush Resonator Delete-Y Pipe Kit replaces the restrictive factory Mid-Pipe Resonator on your 2015-2020 EcoBoost Mustang to reduce back pressure and increase exhaust flow. After installation, you will experience a noticeable increase in horsepower, torque and overall engine performance.

      Muscle Car Rumble. Roush Performance's free flowing Y-Pipe for the EcoBoost Mustangs not only increases power, but it also adds a muscle car rumble to the sound of your exhaust with its classic "Y" crossover pipe design.

      Reuses Stock Cats. This Roush Performance Y-Pipe requires cutting and removal of the factory mid-pipe resonator and simply clamps in place reusing the stock clamps. Best of all, it reuses your original factory catalytic converters, saving you money and keeping you smog legal at the same time.

      Lightweight. The Roush Performance Cut and Clamp Y-Pipe is about 12 lbs. lighter than the factory mid-pipe resonator. It's perfect for street, track and drag racers who are looking to shed unwanted weight in the pursuit of quicker times.

      Stainless Steel Construction. Manufactured from 2.25" diameter free-flowing mandrel bent stainless steel tubing for its durability and corrosion resistance, this Roush Performance Y-Pipe will improve exhaust flow and last a lifetime.

      Application. The Roush Performance Cut and Clamp Resonator Delete Y-Pipe is specifically designed for use on 2015-2020 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine, including Fastback and Convertible models.
