rear muffler hangers

["Lebens, Rick J" <M245884@flt-test-02.mdc.com>]

While changing the rear pads on my 1991 90 Quattro 20v I noticed the inlet pipe of the 
rear muffler in close proximity to the drive flange on the rear differential.  One of 
the rubber hangers broke on the rear muffler and allowed the pipe to contact the 
rotating flange when under loads of greater than one G.  It wore a hole through it.  
I wonder what that will cost come inspection time?

I would recommend other owners on the list with similar vehicles to check 
the donuts on the rear muffler for rotting and deterioration.  The two dollar 
hanger is a lot cheaper than a new rear muffler.
