***Due to high demand and supply chain delays our manufacturing lead times are longer than the normal 6 weeks. Expect a minimum of 8-10 week lead time on all Kooks products. We appreciate your patience as we diligently work to fill your order. ***

HUGE POWER GAINS! Kooks custom headers are in our opinion the best header on the market. The kits come complete with everything you need even O2 extensions, gaskets, and a mid pipe! The custom headers are made of stainless steel and have a 1 3/4 primary tube. Because of the 02 sensor location these headers are very tune friendly.

Tested on our 2011 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!

You may also want to add a pair of the Brenspeed O2 Risers from the drop down menu above if your Mustang needs to pass emission testing.  This will raise the O2 sensor out of the airflow to help with Cataylst errors.

  • 1 3/4" Primary Tubes
  • 304 Stainless Steel
  • Includes necessary installation hardware and gaskets
  • Includes O2 extension harness.
