Description

The Kooks 11422400 headers are engineered from durable 304 stainless steel, featuring 3/8" thick laser-cut flanges for a precise fit and 1-7/8" mandrel-bent primaries. These long tube headers are specifically designed for the 2011-2014 Ford Shelby GT500 models equipped with the 5.4L or 5.8L 4V engine. Installation includes a stock bolt pattern and comes with an EGR fitting, PY-8034-AL gaskets, two CAS-109203 oxygen sensor extension harnesses, and BK111 & BK114 bolt kits. A Kooks X-Pipe or H-Pipe is required for installation. Buyers can also opt for a tumbling service to smooth and refine the stainless steel, removing burrs and weld discoloration.
