Kooks 1-7/8" Super Street Series stainless headers — designed for a healthy power gain without requiring a custom tune. No tune required. The Super Street design preserves enough OEM-style backpressure characteristics that the factory ECU calibration stays happy while still freeing real power from the cast manifold restriction. 304 stainless construction with 3/8" thick laser-cut flanges and mandrel-bent primaries handles sustained heat and corrosion.
Fits 2011-2014 Ford Mustang GT 5.0L (Coyote) and 302 Boss Edition. Round port, stock bolt pattern bolts directly to factory Coyote cylinder heads. No O2 extension harnesses required for stock-tune operation.
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 salt-belt corrosion.
Includes PY-8025-AL gaskets and SB-B60049 bolt kit required for installation. No additional parts required — these connect directly to the OEM exhaust without modifications, which is what makes them a no-tune bolt-on.
