    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 2015-2018 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 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.

      Fantastic quality!

      So the downpipes are very nicely made, fitment was perfect. I'm giving it 5 stars only because of how well made this exhaust is. Let's talk about sound, I have the 4 inch heartthrob setback. The downpipes make it sound awesome from idle to 4000 rpm. Anything after 4000 rpm it sounds extremely ricey. I'm going to install a 4 inch resonator and see if that helps with the from and sound. The drone is terrible at 1500-1750rpm Anything after that you can't even hear the exhaust.

      Turbos are Lit

      Let's those turbos sing and definitely improves air flow and throttle response. Only complaint is I wish they utilized both existing exhaust hanger brackets. I installed downpipe with stock muffler and so excited that it's only louder under acceleration. Great quality product and quick shipping.

      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!
