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

    Quality Construction. Kooks Long Tube Exhaust headers are manufactured from 1-3/4" X 3" 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 1-3/4" 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 matching Kooks Shorty Mid-pipe 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. Does not include a provision for EGR.

        I love the sound of h-pipes with long tubes, but I only see a matching x-pipe available. Can these be used with say the BBK H-pipe?

        • You can use the BBK h-pipes with these headers. However, due to the different brands the fitment may be off and some modifications may be needed.

        What is the difference between this set and your other set MPN# 11222210? The description looks the same to me but they are quoted different.

        • MPN #11222210 will include provisions for EGR while MPN #11222200 will not include provisions for the EGR.

        ARE these emisión legal in New Jersey

        • These Kooks long tube headers may be legal in New Jersey as long as your exhaust setup has catalytic converters in the mid-pipe, however, we would highly recommend checking with your local emission station.

            Love the look and sound

            It has a alot deeper sound and aggressive tone than stock for sure! I didn't want to spend that much but it was a good investment for force induction applications.

            Kooks Headers

            These headers are far superior to the stock headers. The sound from the the kooks headers are more aggressive than stock. Would definitely recommend you get some!!!!
