Oh aye, nothing to say about that.  The boxer exhaust systems are
rigidly mounted to the engines with struts everywhere, but I've never
seen a diesel one.  Clearly if there's a flex joint then there's
expected to be movement between engine and exhaust, and that's where
the rubber comes in.

But I'm a crusader about stress concentrations (waves flag).
