      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 factory manifolds, boosting your Pony's horsepower and torque numbers.

      Quality Construction. Kooks Long Tube Exhaust headers are manufactured from 1-7/8" 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 1-7/8" Headers are designed to fit the 2007-2010 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.

        A must have!!!

        A well made piece that sounds can definitely tell the difference in acceleration and after 3000RPM...if you love loud and raspy this is the setup for you!! My 07 GT500 sounds like an ANIMAL now!!

        Not too bad to go in but rub on steering shaft and on my A arms both sides had to grind it down and then add washers to my engine mounts to clear steering shaft for the cost of that and you would not think you had to modify them

        Amazing Product

        These headers are amazing quality. Paired them with the Kooks 3 In. O/R H pipe and Borla S-type and have one of the best sounding GT500s I have heard in person. Install was very time consuming, but me and two of my buddies knocked it out setting aside a few hours over a few days in my garage on some jack stands with common tools. Hardware that is included is top quality too. Overall a VERY NICE set of headers. does not make the exhaust drone at all but everyone will know when you floor it. Would recommend this tho everyone trying to get great HP and deep sound!
