HUGE POWER GAINS! Kooks custom headers are in our opinion the best header on the market. The kits come complete with everything you need! The custom headers are made of stainless steel and have a 1 7/8” primary tube. These headers are very tune friendly.

Tested on our 2013 5.0 Test Car we picked up a whopping 25 rwhp peak vs. peak and at higher RPM's of 6,800 the gains were just over 30 rwhp. We tested the catted version, design would gain even a few more ponies but at the same time make the car even louder than the high flow cats.

Included in this package is a high flow catted X or H pipe (Use drop down to choose mid pipe). The high flow cats offer enough protection to pass the sniff test yet flow very close to an design. We run Kooks high flow cats on our 2011-14 Mustang GT street cars!
