Yes, probably, but I see your point.

The real "killer" in my exhaust attempts was the cat. w/o a cat, I
could've designed the exhaust like the diesel Vanagon. (two supports
to muffler as I have now) To further show how a poorly supported
exhaust will fail, here's images of undersized poorly designed
brackets in V 1.0 These are now "painful" or me to look at:

They died in less than 1000 KM's. A hard way to learn!

Did the Diesel Vanagon exhaust use isolators merely to limit transfer
of muffler noise?  I imagine not, as engine noise-vibration is
somewhat arrested at the engine and transmission mounts, but have to
ask.
