    More Horsepower and Torque. A set of Kooks Long Tube Headers will greatly improve the performance of your 5.4L F-150. Kooks Headers feature an integrated venturi style collector that increases exhaust scavenging, and reduces turbulence to improve your 5.4L exhaust flow over the restrictive stock manifolds, boosting your truck's horsepower and torque numbers.

    Quality Construction. Kooks Long Tube Exhaust headers are manufactured from 1-5/8 in. mandrel bent 304 stainless steel tubing for superior airflow. These headers are TIG welded and feature a leak-free ball flange design for optimal performance and a better than OEM fit. Stainless steel hardware and gaskets are included.

    Natural Finish. These Kooks Headers feature a natural stainless steel finish, which provides an aggressive appearance to your engine bay. This is not a heat-resistant coating, AmericanMuscle recommends the use of Exhaust Heat Wrap for high performance applications.

    Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a custom tune with a Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

    Application. These Kooks 1-5/8 in. Long Tube Headers are designed to fit the 2009 to 2010 F-150s equipped with the 5.4L engine. Kooks long tube headers require the use of a Kooks "Y-pipe" midpipe in order to be installed properly.

    Ask a Question

    Is these headers fits DIRECTLY to the f150 manufactured y pipe ? not the special y pipe comes with kooks or any other after market products.


    • These Kooks 1-5/8 in. Long Tube Headers are specifically designed to work with their own "Y-pipe" mid-pipe in order to be installed properly. They may fit with other y-pipes, however, due to differences in manufacturing, those other mid-pipe may not properly mount.
