Description
More Horsepower and Torque. A set of Kooks Long Tube Headers will greatly improve the performance of your modular 4.6L 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 2005-2010 4.6L GT Mustangs equipped with an automatic transmission. 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.

Mustang Power

Kooks long tube headers and xpipe should had been the first upgrade i made on my car. the headers with the xpipe combo give my car the retro muscle car sound it should have came with from the factory.

    Mustang Power

    Kooks long tube headers and xpipe should had been the first upgrade i made on my car. the headers with the xpipe combo give my car the retro muscle car sound it should have came with from the factory. not only can you hear the power being made, you can feel it now. back it behind a bama tune and you can't go wrong. best part it's made in the USA.

    Kooks LT

    I purchased the Kooks Long Tube Headers for my 2007 Mustang GT, I combinted this with a Kooks catted H-Pipe that I purchased from Brenspeed, since AM does not carry them. I had the LT's installed by Lamotta's in Longwood, FL, they did a great job with the install. I have the Kooks LT Headers, Kooks Catted H-Pipe connected to my Borla catbacks, the combination was flawless and the sound was amazing. I decided to go with the Catted H-Pipe over the X-Pipe since I prefer the strong and steady rumble of the H-Pipe over the rapsy X-Pipe. Performance gains were evident in the way the car launches and gets up to speed, it really moves and breathes much better, and the sound is amazing. I highly recommend Lamotta's for any install if your near Longwood, FL, they also handled my install for my Steeda CAI, Steeda Springs, Struts and Shocks.
