Kooks 1-7/8" x 3" stainless long tube headers for the Coyote-swapped Fox Body or SN95 running an automatic transmission. The 1-7/8" primary is the right step up for supercharged or aggressively tuned Coyote swaps where the smaller primary becomes the next restriction. 16 gauge 304 stainless construction handles the underhood heat and underbody corrosion that quickly destroys mild steel swap headers. Mandrel-bent primaries preserve flow through every curve.
Fits 1979-2004 Ford Mustang (Fox Body or SN95) with a 5.0L 4V Coyote swap and a 10R80, 6R80, or MT-82 transmission with OEM-style bellhousing. Designed around the Maximum Motorsports K-Member (PN: MMKM-2.1) and standard 4.6L motor mounts (Maximum Motorsports PN: 6-504-BL). The K-member, motor mounts, and headers were engineered together as a system — confirm all three components before ordering. Plan the chassis geometry carefully on any swap of this scale.
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 shrugs off the thermal cycling and salt-belt exposure that destroys mild steel headers within a season or two.
Header gaskets and bolts needed for installation are included. For replacements, order SS-755392 gaskets and BK109 / BK112 bolt kits. Pair with Kooks Coyote-swap connection pipes (PN 10503102) to complete the mid-section, then a 3" tailpipe section downstream.
