I would say:
in general, if you run stock engine mounts and your exhaust hangers are in good condition, you are fine.
If you have a car with higher mileage (75k+ or more) then some of the rubber hanger should be replaced on the exhaust.
Just keep in mind: there's two flex sections on the entire stock exhaust: factory exhaust manifold, and the donut gasket. The more solid everything is, the more likely a failure may occur. But, say the probability of something breaking is 0.5%, you may increase this risk to perhaps 3% and it can still be perfectly fine on your car for many years.
As is the case with many other things, YMMV (Your Mileage May Vary)
Additional NVH into the cabin is a secondary concern, IMO.
