Thanks for your suggestion Dennis. But if an exhaust is "hard mounted"
to a 4 cylinder inline gas engine, is there a greater risk of
transmitting more engine vibration to exhaust thus causing a part(s)
in exhaust to crack? My observation being that the I4 has more
vibration than the WBX.

Originally I used 3 isolators as per the Diesel Vanagon, now I use
four; two per each set of DV type driver side brackets. The muffler is
*very* stable. Possibly as stable as per what you suggest?

I've built at least 4 different versions of exhaust. FAS (Foreign Auto
Supply) hangs their exhaust much like a normal passenger car:
downpipe, flex joint(s), remainder hung from body.

A few images of the FAS exhaust from their Beta picasaweb album starting here:

IMO, their entire album is worthy viewing: http://tinyurl.com/lu6fz99

This shouldn't be "rocket surgery" but as Don and others have
experience, getting the exhaust system set up to last a long time is a
challenge.
