The exhaust on my '84 mk2 polo seems to have a lot of play. When going over a bigger bump or hole in the road  I get a terrible screeching noise of metal on metal.
My guess is the muffler slams the body, the 2 old donut rubbers that it hangs by are very worn. A parts dealer in my area gave me new rings, OEM-matched using my number plate.

But the new rubbers seem smaller and are nowhere as flexible as the old ones. Wrong part? I can't possible put on both rubbers now by hand, there is way too much tension.

Pop the end of something like this through the hole, make a loop that you can get a good hold of, or even a foot into, then use some of your larger body muscles to stretch the thing into position.

I use a tent peg with a 90 degree bend in it. Works well. If you haven't got one, you could also loop a couple of cable ties through to make a handle and cut them off after.

 

Also, throw the rubber in a mug if hot water for 10 minutes to soften it up.
