The Dorman 674-310 is a manifold converter: a stainless steel exhaust manifold and catalytic converter built as one bolt-on unit for specific vehicles. It is a direct-fit replacement for the original part, with a flanged single inlet and outlet, a sensor port and a gasket in the box. It suits owners facing a cracked manifold or a failed converter who want one part instead of two. Against OEM parts it is the budget option, and against universal converters it fits without fabrication, though it only fits the vehicles Dorman lists.
