The JBA Cat4Ward shorty header for 2015–2022 Ford Mustang 5.0L Coyote uses 1-3/4" primaries in raw 409 stainless. These headers reduce restriction compared with factory manifolds to improve exhaust flow and engine efficiency. The Firecone collector applies race-proven tuning for better torque where you use it, and mandrel-bent tubing, 3/8" machined flanges, oversized ports and extra-thick collector domes combine with factory-style emission connections for clean installation.
