haha, mine was doing the same thing. Goto the auto store and buy some exhaust turn downs. just a pipe that diverts exhaust downward toward the ground. Install them. Then pull downward on your exhaust mounts and try to get the exhuast to drop a quarter inch away from the bumper.

Mine started to melt too, but its cause i had a ghetto exhaust. I got pissed and now I have no exhaust. But thats ok, because I have no transmission either. lol

You could always rivet a metal plate...

First, is the tailpipe touching the bumper? Then the exhaust system should be checked. Maybe you backed into something and bent the tailpipe(s). If so bend them back down.

If it is just heat from the exhaust gasses, how well is the car running? Maybe it needs a tune-up and some fuel system maintenance.

You could also use this old school trick. I haven't seen it in a while but Trans-Am, IMSA, and SCCA guys used to cut aluminum or stainless steel sheet into heat shields and rivet it on rockers or bumpers above exhaust pipes.

Well I've seen them before on RX-7's. Basically it's just a curved piece of metal that is clamped or bolted on to the bumper somehow. I always thought it was to keep the flames from cooking the paint on the bumper.

Yeah, it was sheet aluminum or steel cut to fit the exhaust cutout and riveted. You should use a grinder or sander to smooth the cut edges (wear gloves...) and drill holes in the metal and the bumper for rivets.

You could use self-tapping screws to save on the drilling and riveting...

or, you could use that self-adhesive heat shield sound insulator stuff people use in the cockpit and around speaker boxes.
