Our take on the Dorman 674-310 Catalytic Converter with Integrated Exhaust Manifold

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.

Questions and answers

Does it fit my car?
Only if your year, make, model and engine match Dorman's application list for 674-310. Check the part number against your vehicle before ordering; it is not a universal fit.
Is it legal in California?
Not necessarily. California and some other states require CARB-approved converters, and this part is not sold as one. Check your state's rules before installing.
What is in the box?
The manifold converter unit and the outlet gasket. You reuse the existing sensors and hardware unless they are damaged.
Do I need to weld it?
No. It is a flanged bolt-on replacement for the stock unit, so it installs with hand tools if the old fasteners come free.
Will it fix an exhaust tick?
Yes, if the tick comes from a cracked manifold. A leak elsewhere in the exhaust will need a separate repair.
Does it add power?
No. It is a stock replacement, not a performance part, so expect the same output as the original.
