    More Horsepower and Torque. If you feel your turbocharged EcoBoost F-150 needs more power to pass the slower traffic on the highway or tow your race car to the track, then look no further than the Stainless Works Catted Downpipe. Featuring high flow catalytic converters, this downpipe completely replaces your factory downpipe and power robbing catalytic converters. By relieving some of the restrictions around the turbos and reducing back pressure, it increases your exhaust flow which will result in more horsepower and torque. Not only will this increase your performance, it also adds an aggressive exhaust note to your rig, when compared to the stock down pipe.

    Stainless Steel Construction. Stainless Works constructs this Catted Downpipe from 3 in. diameter T304 stainless steel tubing for its strength and superior corrosion resistance. This Downpipe is also mandrel bent to provide superior airflow, so there are no kinks to rob you of power.

    Required Upgrade. For proper operation and maximum power potential this Downpipe will require reprogramming the vehicles computer. AmericanMuscle recommends a custom tune with a F-150 Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

    Application. This Stainless Works 3 in. Catted Downpipe is specifically designed to fit the 2015-2018 F-150 equipped with the 2.7L or 3.5L EcoBoost engine with either a factory catback or an aftermarket catback utilizing the factory connection. It is not compatible on the Raptor models.

    Technical Note. This Stainless Works product is not legal for use in California or other states adopting California emission standards.

    After I install the downpipe, will I have a check engine light come on? Do I have to purchase a tuner?


    • To have this downpipe correctly used, you will need a tuner a recalibrate the vehicle so that the check engine light does not come on.

    Hello, I have a 2016 Ford F150 2.7 ecoboost. I already have a 4" mangaflow cat back exhaust on it, I was just wondering if this downpipe will be to much air flow for this 2.7 ecoboost engine? Thank you for your time.


    • This Stainless Works Catted Downpipe will work with your 2016 2.7 EcoBoost F150. However, it will require a re-tune because of how much air flow it will be generating.

      It's almost perfect

      This catted downpipe is great but the only issue I had to deal with was I needed a seal at the flange for the catback connection. But I easily made one. Along with complementing my catback exhaust and power numbers it really screams and runs great
