An OEM Grade Federal EPA compliant direct-fit converter assembly, 48.5 in overall with two flanged inlet connections, a 2.5 in inside diameter outlet and two oxygen sensor ports, one before and one after the substrate. The front section is an oval clamshell and the rear a round spun body, both 409 stainless with 308 stainless MIG welds, and mandrel-bent tubing keeps the factory exhaust geometry so flow and fuel trim stay where the calibration expects them. It bolts in with no cutting or welding. This is a federal EPA part and is not legal for sale or installation in California, Colorado or New York.
