When I installed my Apex'i WS, due to the larger diameter than stock piping, it hit the bottom of the Skunk2 SS.
First thing I did, of course, since I was still under the car, was bend the metal hanger posts on the exhaust. That fixed the problem.
Of course, I bent the posts up, so that the exhaust would hang lower. You could try to do the opposite: Bend the posts down, so the exhaust doesn't hang so low.
OK, then I got my high-flow cat, which ended up moving the whole exhaust towards the back of the car by a fraction of an inch. So now the exhaust was rattling on the heat shield on the gas tank.
So I roughly measured the existing rubber hangers, went to Pep Boys, and bought longer rubber hangers. Pep Boys had about 4 or 5 different sizes. I think I ended up getting the hanger for a Ford pickup. That big hanger had several different holes/openings. If I had used the furthest-apart holes, the exhaust would have been hanging very low. I ended up using one hole and one opening. Since the opening is way larger than a hole, I used part of the old rubber hanger to fill the void of the opening, so that the rubber hanger wouldn't fall off.
As for rubber vs. polyurethane.... dunno. It was hard, black and rubbery. Could have been polyurethane. People say to upgrade to polyurethane bushings for motor mounts, shifter bushings.... but I've never heard of upgrading to polyurethane for the exhaust hangers.
Sorry to ramble....
