2011-2014 F150 3.5L EcoBoost Downpipes & Mid-Pipes

F150 EcoBoost Downpipes and You!

Downpipes, and their accompanying custom tuning, offer up some of the best bang-for-your-buck horsepower that you can find out there on the market, however, choosing any particular downpipe can make your head spin. Each of these EcoBoost downpipes are a little bit different than one another, though they'll all get you impressive power gains. All of the pipes either come in off-road or catted flavors. F150 EcoBoost off-road downpipes get your truck the most power out of the two options, but tend to suffer from a louder tone, drone, and rasp that not everybody is a fan of. Catted downpipes come with some sort of catalytic converter which provides less drone and rasp than off-road pipes at the expense of some amount of power. The Kooks GREEN Catted Downpipe is even EPA-certified 48-state legal, and will pass emissions in every state except California, New York, or specific places that have adopted CARB emissions standards.
