      Improved RWHP and TQ. Designed as a direct fit replacement on your 2.3L EcoBoost Mustang, this BBK Catted Down Pipe offers improved rear wheel horsepower and torque as a result of its larger diameter tubing. This aluminized 3" Down Pipe also features a high flowing catalytic converter to help increase the overall performance of your turbocharged S550 Mustang.

      More Aggressive Sound. Not only will this BBK Catted Down Pipe help increase the power of your Pony, but it will also add a more aggressive exhaust note compared to the stock down pipe. Make sure everyone hears your 2015-2023 EcoBoost coming down the road with the addition of this high quality down pipe.

      Aluminized Steel Construction. Manufactured to provide maximum exhaust flow and performance, this BBK Down Pipe features 3" diameter CNC machined mandrel-bent aluminized steel tubing. Complete with a high flow catalytic converter, this Down Pipe would be a perfect fit and complement to either the stock catback or an aftermarket catback system.

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

      Application. The BBK 3" to 2.25" Catted Down Pipe is designed to fit all 2015-2023 EcoBoost Mustangs equipped with the turbocharged 2.3L engine. This Down Pipe can be installed with either the factory or an aftermarket 2.25" catback exhaust.
