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.

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.

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