Kooks 2" x 3" stainless long tube headers — the largest primary in the Coyote lineup, built for serious power builds where peak HP lives high in the RPM band and any smaller primary would cost power up top. 304 stainless construction with 3/8" thick laser-cut flanges handles sustained high-output heat. Mandrel-bent 2" 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. Best suited for naturally aspirated builds with extensive cam/head work or serious forced-induction setups.
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 roots were established. 304 stainless construction stands up to thermal cycling and 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) and a 3" race exhaust downstream.
