Kooks 1-7/8" x 3-1/2" stainless long tube headers with a 3" inline bolt pattern at stock port height. The 1-7/8" primary delivers broad mid-range with healthy top end on a built 351 — a versatile size that works for naturally aspirated builds and mild forced-induction setups. The 3-1/2" collector gives the engine room to breathe at the top of the band. Mandrel-bent primaries and 16 gauge 304 stainless construction preserve flow and durability.
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 racing heritage was established. 304 stainless construction holds up to thermal cycling and salt exposure that destroys mild steel headers in a few seasons.
Gaskets and bolt kit required for installation are included. Pair with a matching Kooks 3-1/2" connection pipe or X-pipe and a downstream 3-1/2" race tail section. Replacement gaskets (PY-8013-AL) sold separately.
