Have any one here used DORMAN's manifolds (Part # 674232) and know if it's any good ?

All the aftermarket exhaust manifolds are made in China. Whether they all come from the same factory or not is unknown; it is extremely difficult to chase parts back to their actual origin in China. Dorman is a reputable vendor. Quality of the aftermarket manifolds is generally not quite as good as an original Chrysler manifold, but certainly acceptable. You may have to do a minor amount of grinding to remove casting lines that might interfere with your easy access with a wrench to the studs, nuts, and washers.

It is very much worth your while to get the good gaskets for the manifolds-to-head and intake-to-exhaust junctions.
