Kooks 2017+ Ford F150 Raptor EcoBoost 3.5L V6 3in Stainless GREEN Catted Turbo Down Pipes
Powerful Kooks "GREEN" Catted DownpipesThe factory down pipes and stock catalytic converters on your 2017-2018 Raptor 3.5L EcoBoost are the most restrictive parts of your off-road 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 EcoBoost Raptor performance parts.
Larger, More Efficient Stainless Steel TubingKooks 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.
