The Stainless Works long-tube header for 1979–1993 Ford Mustang applications features 2-inch primaries to increase exhaust flow over stock manifolds. As a direct-fit header, it aims to reduce backpressure and improve cylinder scavenging for better throttle response across the rev range. This option is suitable for classic Mustang owners seeking a larger-diameter primary for greater flow capacity.
