A word of advice... don't get the polyurethane exhaust hangers. I had some for about a year and then I started noticing a rattling sound at certain RPMs and over imperfections in the road. I spent a very long time tracking this rattle down and it ended up being the polyurethane hangers rattling.

What happened is the holes where the metal exhaust hanger pegs go through the bushing widened over time, and the bushings became harder over time, possibly from the heat. As a result, the engine vibrations caused the metal peg to rattle inside of the hole in the bushing. The noise was extremely annoying. If anything, I just recommend buying a brand new set of rubber bushings. You can get them cheap at the auto parts store.



EDIT: After reading through your thread I noticed that you actually bought some from me... the ones I had leftover a while back. (right?) I didn't know about this problem when I sold those to you... I just got rid of my other ones about a month ago or so. Went back to rubber. If you notice a rattling and it bothers you, check there first.
