MagnaFlow's OEM Grade manifold converter replaces the factory close-coupled converter and exhaust manifold as a single one-piece bolt-in unit, so no cutting or welding is required. The spun body uses 16 gauge 409 stainless steel tubing with 308 stainless steel MIG welds over a ceramic substrate, measuring 17.375 in overall with a 7.25 in converter body, flange inlet and outlet connections, and one oxygen sensor port. A flat ring gasket, a flange gasket, three bolts, and three nuts are included. This converter is built to Federal EPA standards and is not legal for sale or installation in California, Colorado, or New York.
