Description
More Horsepower and Torque. A set of Kooks Long Tube Headers will greatly improve the performance of your 4.6L GT or Bullitt Mustang. Kooks Headers feature an integrated venturi style collector that increases exhaust scavenging, and reduces turbulence to improve your 4.6's exhaust flow over the restrictive stock factory manifolds, boosting your Pony's horsepower and torque numbers. Quality Construction. Kooks Long Tube Exhaust headers are manufactured from 1-5/8" 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.

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 Bama 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 1996-2004 4.6L GT and Bullitt Mustangs. Kooks long tube headers require the use of a Kooks shorty midpipe in order to be installed properly (see drop down option above). O2 Sensor extensions are included.

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

    What a Pain! But Good.

    Ok, the good. These headers arrived very quickly being sent overseas. Three days quick. A new record AM! The look and finish on them is amazing despite the fact that you'll never really see them again once they are on the car. The bad (or very irritating) - The directions that Kooks include with these are very basic. Very basic. Some of the steps they have if you follow make putting them in and tightening the bolts near impossible. Even after a call to Kooks the tech I spoke with said it is better to drop the K-member and use quality sleek tools. Having to "slightly pry" two of the tubes apart to get the steering column in is a joke. Better to disconnect the steering column underneath the steering wheel and slide it through said tubes and reconnect it. And lastly, the o2 extensions didn't even match the o2 sensors at the connection point. There are two tabs that are supposed to help guide it in and they didn't line up. I ended up breaking those tabs off, luckily had a clean break, and they slid right in. Overall, if you're more experienced at doing this work or are going to pay a shop to do it, they are worth the money. But, if you do it yourself, be prepared to deviate from some very poor instructions.
