The Stainless Works long-tube header for 1979–1993 Ford Mustang applications uses 1-7/8-inch primaries to replace restrictive factory manifolds and improve exhaust scavenging. Intended as a direct-fit performance header, it opens up flow to help reduce backpressure and support stronger midrange response without altering core engine layout. It suits restorations and period-correct performance upgrades.
