Almost no RWD layout vehicles have them and only 2/3 of FWD vehicles do

Well that pretty much clinches it then. The rubber mounts would absorb minute changes anyway. Wait a sec...do all cars use rubber mounts for their exhausts? All mine have, but I've only had a few vehicles.

nope all of ours use at least one solid mount. tyically near the cat. the rest are rubber from there back tho.

fyi not even the model A had solid mounts, just a strap looking thing that would allow it to jiggle. also has the exhaust manifold flange look like the flexable lead doughnuts some modern cars use
