While we had confirmation of cat-back exhaust fitments for up to the 2017 3.5L EcoBoosts for a good while now, downpipes were questionable. With a new transmission and revised motor, many manufacturers were concerned that changes would have to be made. However, those fears have come to pass, and it's confirmed that all of 2015-2016 F150 3.5L EcoBoost Downpipes now fit to the 2017 3.5L EcoBoost F150 model year. While that's certainly great news, there is a slight hiccup in that SCT still does not have tuning support ready for the 2017 F150s and Raptors with a 3.5L EcoBoost. Hopefully that rolls around sooner, rather than later.
