    Increase Power and Performance. Add even more horsepower and torque to the rear wheels of your 3.5L EcoBoost powered F-150 by installing a Kooks Off-Road Down Pipe. A Kooks Off-Road Down Pipe eliminates those power robbing stock catalytic converters to release all the hidden power of your F-150 has to offer.

    More Aggressive Sound. Kooks Off-Road 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 Off-Road 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. Off-Road Down Pipe is designed to fit 2011 to 2014 F-150 powered by the 3.5L EcoBoost engine.

    Technical Note: Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    Is there a particular reason this will not fit the 3.7L? Exhaust should be the same as the 3.5L, correct?


    • This specific piece is only designed for the EcoBoost models.

      Great product

      I changed out only my downpipes and left the rest of the exhaust factory. Didn't make it annoyingly loud, just right
