    More Horsepower and Torque. A set of Kooks Long Tube Headers will greatly improve the performance of your Mach 1 or SVT Cobra Mustang. Kooks Headers feature an integrated venturi style collector that increases exhaust scavenging, and reduces turbulence to improve your DOHC 4.6L'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 1-5/8" 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. 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 Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

    Application. These 1-5/8" Kooks Long Tube Headers are designed to fit the 1996-2004 Mach 1 and SVT Cobra Mustangs equipped with the DOHC 4.6L modular engine. 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.

      Awesome sound!

      Very difficult to put on my 2004 Cobra. Look great!

      Kooks LT

      Great product. You must drop the K member to install. Once that is out relatively simple. Gain will come with more horsepower but I could tell a pretty good throttle response. Worth the money.

      Great Sound and Power

      I paired these headers with the matching Kooks Offroad X-Pipe leading out to Magnaflow Magnapacks and the power and sound increase was amazing. The higher the rpm's the better the sound gets. Its almost too mean sounding for the streets lol. Im 19 with little mechanical experience and I managed to install them on my own in my garage over a weekend. So don't feel like its absolutely necessary to pay a shop for the install. The fit was spot on.
