Kooks 1-7/8" x 3" stainless long tube headers for built Coyotes — supercharger, big cams, headwork, or any combination where the 1-3/4" tube becomes the bottleneck. The 1-7/8" primary keeps the upper RPM range open on serious Coyote builds making power well above stock. 304 stainless construction with 3/8" thick laser-cut flanges handles sustained high-output heat. Mandrel-bent primaries preserve flow through every curve.
Fits 2011-2014 Ford Mustang GT with the 5.0L 4V Coyote. Requires a Kooks X-pipe or H-pipe with a 3" inlet. Round port, stock bolt pattern bolts directly to Coyote cylinder heads.
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every Kooks header is welded by experienced fabricators in the same shop where the company's racing legacy was built. 304 stainless construction stands up to thermal cycling and salt-belt corrosion.
Includes PY-8025-AL gaskets and BK109, BK112, and BK114 bolt kits required for installation. Pair with a Kooks 3" X-pipe (PN 11413100) or H-pipe (PN 11413400), plus an appropriate cat-back downstream.
