The Kooks Catted Down Pipe features "Green" 49 State EPA certified high flow catalytic converters to increase the overall performance of your F-150.

    More Aggressive Sound. Kooks Catted Down Pipe not only helps increase power and performance, but it also adds a much more aggressive exhaust note to your 3.5L EcoBoost F-150, when compared to the factory down pipe.

    Stainless Steel Construction. Constructed from 3 in. diameter free-flowing mandrel bent 304 Stainless Steel tubing for superior strength and corrosion resistance, this Kooks Catted Down Pipe will improve exhaust flow for more power.

    Recommended Upgrade. To realize the full power potential that this Down Pipe has to offer, AmericanMuscle recommends a custom tune to reprogram the vehicles computer (ECU) for proper operation.

    Application. This Kooks 3 in. Green Catted Down Pipe is designed to fit 2011 to 2014 F-150 powered by the 3.5L EcoBoost engine.

    Technical Note: The Kooks Ultra High Performance Green Catalytic Converters are 49 State EPA Certified, so they will pass most states emissions testing procedures. However, you should check your local and state ordinances for installation and usage regulations.

    Ask a Question

    Is California the one state it's not legal in?


    • Unfortunately, the Kooks Green Catted Downpipe was not approved by the California Air Resources Board, and it would be considered illegal for road use in the state of California.

    Is this one illegal in any states, or will not pass emissions in any states?


    • This downpipe is EPA certified in 49 states so they will pass in most states excluding those who are adopting the extremely strict regulations. Please check with your local and state ordinance laws for further information.

      Loved, but misleading

      I love my new Kooks catted green downpipes but the description is misleading they start off as two and a half inches from the turbo down maybe two six inches and then it turns into three inches. Noticeable power straight from the gate.

      More POWER!

      If you want to make more power and reduce exhaust temperatures, you need this downpipe. Great fit and a moderate install time of about 2.5 hours. 5 stars and two thumbs up,
