This is the driver side underfloor converter for the 5.7L V8, the only converter on that bank, and it carries CARB Executive Order D-193-197 for legal installation in California and the states that follow California emissions rules. The 49.25 inch spun body is built from 16 gauge 409 stainless steel tubing with 308 stainless steel MIG welds, OE-sized 410 stainless barbed hangers and a ceramic substrate, and bolts in flange to flange with no cutting or welding. Two sensor ports, pre-converter and midbed, return the factory oxygen sensors to their original locations so the engine management system stays in closed loop and the check engine light stays off. A flange ring gasket is included.
