PRODUCT DESCRIPTION

Kooks Headers & Catalytic X-Pipe Kit
Get more horsepower from your 2011-2014 Shelby GT 500 with a set of Kooks Headers and catalytic X-pipe. These Kooks long tube headers for your 2011-14 Shelby GT500 features 304 stainless steel tubing, 1 7/8" primaries, and 3" collectors with O2 bungs welded in. Kooks builds all of their products to the highest standard, and these are quite possibly the best long tube headers you can buy for your 5.4L 4V GT500! This kit also includes a Kooks 3" crossover x-pipe which is designed to connect your new Kooks long tube headers to your factory exhaust. This all 304 stainless crossover includes high flow catalytic converters along with all clamps and gaskets needed for installation!

What Sets Kooks Apart?
-Kooks is known for building the best high end consumer headers in the world. This header is constructed with the below high end features!
-Tig welded with all 304 (aircraft grade) mandrel bent stainless steel construction
-Integrated venturi merge spike for better savaging and less collector turbulence
-Primaries blended into the flange for better flow
-Leak Proof Ball Flange collector for trouble free ownership.
-Each primary tube is one continuous piece of tubing. Some competitors weld several pieces of tubing to create one primary, which is a weaker design.

Quite simply...there is not a better header on the market!

Installation/Tune Note
-Installation of long tube headers will require custom tune to prevent damage to your vehicle. If you already have a custom tune on your Mustang, please consult with your tuner prior to installation and operating your Mustang.
