Kooks 3" "GREEN" Catted Downpipes F150 EcoBoost 2011-2014
Powerful Kooks "GREEN" Catted Downpipes
The factory down pipes and stock catalytic converters on your 2011 to 2014 F150 EcoBoost are the most restrictive parts of your truck's exhaust system and replacing them with something more efficient will open the door for huge horsepower and torque gains. These Kooks catted downpipes have a large diameter and come equipped with Kooks newest "GREEN" high-flow catalytic converters that out-flow your factory converters while being 48-State, EPA-Certified street legal. The Kooks EcoBoost catted downpipe gives you much more power out of the gate and is even more effective when your truck is tuned and stacked with even more F150 EcoBoost performance parts.
Larger, More Efficient Stainless Steel Tubing
Kooks designed these downpipes to fit right in place of your stock downpipes and connect to both your stock turbos and your factory cat-back exhaust kit, as well as most aftermarket cat-back kits designed to install with the factory mid-pipe. Kooks downpipes come with a y-pipe connection and all measure 3" in diameter and are all mandrel-bent instead of crimped to provide superior exhaust flow over your factory system. The downpipes and Y-pipe are made from 304 stainless steel that's resistant to corrosion and discoloration in nearly any climate. The downpipes come with hardware, clamps, and instructions.
48-State Street Legal: these downpipes are EPA-Certified and will pass emissions in 48-states and other areas. These downpipes are not approved for street use in California, New York, or any other area that has adopted CARB emissions standards.
