Kooks 2" x 3-1/2" stainless long tube headers with a 3" inline bolt pattern at stock port height. The 2" primary is the right call when a built 351 is making real top-end power and a smaller primary becomes the next restriction. The 3-1/2" collector ensures the merge point doesn't choke flow downstream of the primaries. 16 gauge 304 stainless construction with mandrel-bent primaries delivers durability and clean flow.
Fits 1979-1993 Ford Mustang Fox Bodies with a 351 (9.5 deck) SBF running Dart & World 210 & 225 or Pro Topline cylinder heads. The 3" inline bolt pattern bolts directly — no adapter plates required. Installation requires a UPR or BMR tubular K-member, Powermaster 9503 starter, and 5.0L / 5.8L motor mounts. Plan the chassis geometry as a system before ordering.
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 NASCAR and drag racing legacy was built. 304 stainless construction shrugs off thermal cycling and salt-belt exposure that destroys mild steel headers in a season or two.
Gaskets and bolt kit required for installation are included. Pair with a matching Kooks 3-1/2" mid-section and a downstream 3-1/2" race tail section. Replacement gaskets sold separately.
