More Horsepower and Torque. Unleash the hidden horsepower and torque from turbocharged powered 2.7L or 3.5L EcoBoost F-150 by installing this Stainless Works Off-Road Downpipe. This Downpipe is larger than stock and eliminates the power robbing factory catalytic converters, which helps to increase exhaust flow and reduce back pressure, to give your truck those power gains. Not only does this downpipe increase your power and performance, but it also adds a much more aggressive exhaust note to your EcoBoost F-150, when compared to the stock downpipe.

Stainless Steel Construction. Stainless Works constructs this Off-Road 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. Off-Road Downpipe is specifically designed to fit the 2015-2017 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 Raptor models.

Technical Note. This Stainless Works product is intended for off road use only, and is not legal for use in emission restrictive states.

    Solid difference in power!

    If your looking for that throw you back in the seat under hard boost, this is sure to do it! Easily one of the quickest bolt on upgrades u pair with a simple tune and bam just like that you feel the power difference and notice the sweet deeper sounding note of exhaust we all miss after switching to a exoboost. Sure not to disappoint you!
