      Description

      More Horsepower and Torque. A set of Kooks Long Tube Headers will greatly improve the performance of your Shelby GT500 Mustang. Kooks Headers feature an integrated venturi style collector that increases exhaust scavenging, and reduces turbulence to improve your GT500'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.

      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.

      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 Shelby GT500 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 Note: This Kooks product is intended for off road use, and is not legal for use in emission restrictive states.

        Kooks headers

        Amazing finish and a fantastic quality. After my Lund tune these headers added 43whp to my 2012 Shelby. Sounds incredible too.
