      More Horsepower And Torque. Add even more horsepower and torque to the rear wheels of your turbocharged EcoBoost Mustang by installing a Stainless Works 3" Performance Catted Down Pipe. A Stainless Works Catted Down Pipe features a high flow race catalytic converter to increase the overall performance of your S550 Mustang.

      More Aggressive Sound. Stainless Works Performance Down Pipe not only helps increase power and performance, but it also adds a much more aggressive exhaust note to your S550 EcoBoost Mustang, when compared to the stock down pipe.

      Stainless Steel Construction. Manufactured in the USA from full 3" diameter T304 stainless steel tubing for strength and superior corrosion resistance, this Stainless Works Catted Down Pipe is mandrel bent for superior airflow - so there are no kinks to rob you of power.

      Recommended Upgrade. To realize the full power potential that this Down Pipe has to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

      Application. This Stainless Works Full 3" Performance Catted Down Pipe is specifically designed to fit the 2015-2023 EcoBoost Mustangs and will require the use of a Stainless Works 3" Cat-Back Exhaust in order to be installed properly (see options above).
