1-3/4" Stainless Long Tube Headers

The Kooks 1-3/4" Stainless Headers are precision-engineered long tube headers specifically for the 2011-2014 Ford Mustang GT equipped with the 5.0L 4V engine. They feature 1-3/4" mandrel-bent primaries that transition to a 3" collector, paired with robust 3/8" thick laser-cut flanges for a secure and leak-free seal. Installation is facilitated by the included PY-8025-AL gaskets and a comprehensive bolt kit (BK109, BK112, & BK114). These headers utilize a stock bolt pattern for easier integration. Please note that these headers require the use of a Kooks X-Pipe or H-Pipe for complete exhaust system compatibility. These headers are built to order in North Carolina, with an estimated ship window of 4-6 weeks. Options for custom coatings, including various Jet-Hot Extreme 1300 Degree Ceramic Coatings, are available for enhanced heat management and aesthetics, as well as a tumbling service. The product page also includes a state of California warning regarding potential exposure to chemicals.
