    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 2015-2019 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.

    5 Top Rated Questions

    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.

    I have the Sct tuner and I got a tune from mpt and they said they won't give a tune to keep the check engine light from coming on, so where can I get the tune for the check engine light?

    • Most tuning companies will not create tunes to delete check engine lights as this violates Federal law/EPA regulations, and there has been considerably more enforcement of these recently.

    Where can you get the custom tune so the check engine won't come on?

    • From my understanding, you would need a custom dyno tune.

    Hi, I’m interested in the Stainless Works Catted downpipes for my F150, but I don’t want to jeopardize the street legality of my truck. In your video you state that the pipes are DOT and CARB approved (12:10 mark in the video) but in the text it says that they are not legal in California and in the questions it says that, even with a custom tune, they might throw a CEL code for inefficient cat. So what exactly is the legal status of these pipes. ( I do not live in California so I don’t care what they do there.)

    • These Downpipes are NOT CARB compliant. Tuning and Emissions: these downpipes will require custom tuning for proper operation and power gains, and they may not meet emissions requirements in your area.

    I'm curious about the reprogramming, I have the SCT SF4/X4 power flash tuner with 4 customs tunes for my 2016 ford f150 with the 2.7 ecoboost. I cant find a recalibrate feature. Do I just redownload my custom tune and that will keep my check engine light form coming on or is there something else I am supposed to do to keep this from happening? Please advise

    • A new custom tune would be required, as the custom tunes do not update for new parts.

    I currently have the MBRP Black Series 3 in. Dual Exhaust System - Middle Side Exit installed on my '16 2.7L F-150. It mentions in the technical notes about the factory connect. I want clarification on this connection/piece seeing I got rid of my factory exhaust. Thank you. 1 answer
    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. 1 answer

      Poor maf hole drilling

      After installation, had to remove bc the maf holes did not line up with threads syncs the threads were only half way drilled on one hole. Had to re tap all holes and grind out the misalignment just to get the maf started in the threads. Took longer to fix the shoddy craftsmanship than to install.

      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
