Kooks 2" x 3" stainless long tube headers — the largest primary in Kooks' Coyote lineup, built for high-output supercharged or naturally aspirated builds making serious power above 6,500 RPM where smaller primaries 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 2015-2026 Ford Mustang GT with the 5.0L 4V Coyote. Requires a Kooks X-pipe, H-pipe, or 3" connection adapter. 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 handles thermal cycling and corrosion.
Includes 755392 gaskets, CAS-105979 and CAS-109677-style O2 sensor extensions as required, and a complete bolt kit. Pair with Kooks Coyote connection pipes (PN 11513100), ULTRA X-pipe (PN 11513700-2), or 3" connection adapters.
