    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 Off-Road Down Pipe. A Stainless Works Off-Road Down Pipe eliminates the power robbing factory catalytic converter to release all the hidden power and performance your S550 Mustang has to offer.

    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 factory 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 Off-Road Down Pipe is mandrel bent for superior airflow - so there are no kinks to rob you of power.

    Required Upgrade. For proper operation and maximum power potential this Down Pipe will require reprogramming the vehicles computer. 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 Off-Road Down Pipe is specifically designed to fit the 2015-2019 EcoBoost Mustangs and will require the use of a Stainless Works 3" Cat-Back Exhaust in order to be installed properly (see options above).

    Technical notes. Not legal for use on pollution controlled motor vehicles; intended for off road use only.
