MagnaFlow's OEM Grade manifold converter replaces the factory close-coupled converter and exhaust manifold on the 2.5L four cylinder as a single one-piece bolt-in unit, so no cutting or welding is required. The spun uncoated body uses 16 gauge 409 stainless steel tubing with 308 stainless steel MIG welds over a ceramic substrate, measuring 23 in overall with a 9 in converter body, flange inlet and outlet connections, and one oxygen sensor port. A crush ring gasket and a flange gasket are included. This converter is built to Federal EPA standards and is not legal for sale or installation in California, Colorado, or New York.
