BBK long-tube header and high-flow catted X-pipe kit for 1979–1993 Ford Mustang 5.0L uses 1-5/8 in. CNC mandrel-bent tubing to promote unrestrictive exhaust flow and broader torque across the RPM range. The kit replaces factory shorty headers and mid pipe and bolts to the factory cat-back. It includes 3/8" laser-cut flanges, a patented scavenging collector, gasketless ball-and-socket connectors, new gaskets and hardware, plus a high-temp titanium ceramic coating and factory-fit catalytic mid pipe for improved exhaust efficiency.
