The Stainless Works long-tube header for 1979–1993 Ford Mustang applications features 2-inch primaries and is intended to replace restrictive factory exhaust manifolds. By opening exhaust flow, this header helps reduce backpressure and supports improved cylinder scavenging and throttle response. It’s presented as a direct-fit upgrade for classic Mustang engines where larger primary diameter is desired for increased flow.
