    Description

    More Horsepower and Torque. A set of Kooks Long Tube Headers will greatly improve the performance of your 5.0L Coyote Mustang. Kooks Headers feature an integrated venturi style collector that increases exhaust scavenging, and reduces turbulence to improve your 5.0's exhaust flow over the restrictive stock manifolds, boosting your Pony's horsepower and torque numbers.

    Quality Construction. Kooks Long Tube Exhaust headers are manufactured from 1-3/4" 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.

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

    Application. These Kooks Long Tube Headers are designed to fit the 2011-2014 5.0L GT Mustangs. Kooks long tube headers require the use of a Kooks shorty midpipe in order to be installed properly (see drop down option above).

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