It was so hard to find in fact that the only way I could do it was to put my self in danger - no pun - and basically had to have the wife rock the car back and forth clutch in and out while revving) as I laid very close to the back end. finally saw the rubbing happening. Took it back to the shop and they cut some material away and it was gone. The shop even thought I was nuts at first until we saw the scratch marks on the muffler. Passenger side was hanging just slightly lower than driver side muffler.

Thanks for the advice, but I already checked for rubbing against the heat shield - nothing.
