MagnaFlow CARB Secondary Underbody Catalytic Converter - Ford F-150 / Expedition 5.4L 1997-1998

These 5.4 litre trucks run four converters, and this is the underbody unit on the left side rather than one of the front pair. It uses a clam-shell stainless body over a ceramic substrate, 30.75 inches long, with a flange inlet, a pipe connection outlet, two sensor ports for pre and post converter positions and an aluminized steel heat shield already attached. Hangers are included and it bolts in with no cutting or welding. It carries CARB Executive Order D-193-176, so it is legal for sale and installation in all 50 states including California, Colorado, New York and Maine.
