The orignal rear cat support was a hard mount that would crack and the cracked bits would hammer on each other. There was no allowance for thermal expantion.... really dumb...let me count the ways....
Anyways, they replaced that design with a conventional rubber hung support. Mine was discovered cracked when some other service was done... fitting the Sports exhaust perhaps.
Speaking of exhaust shields and such:
I found that an exhaust shield mount had cracked through the thin aluminum shield. This was where the exhaust run through the central tunnel does a 90 turn to go around the fuel tank. The shield is not supported on both sides like elsewhere as putting screws into the plastic fuel tank is considered poor practice. So the shield is not rigidly mounted and is exposed to wind buffeting and getting distorted when driving through heavy snow and/or backing out through it. It does not help that it sticks out a bit to catch everything either.
So it mounts between to plated steel fender washers (over sized). One washer has a drawn neck to protude through the shield and the other washer. A nice arrangement. So I took a thicker strap of ~1/16th" aluminum and drilled a 3/8" hole in it and placed it between the steel washers. One end bends up and crimps around the free edge of the shield and the other lies along the trough of the shield to apply a stablizing force on it. So the result is quite rigid and strong.
I also found that the clamp for the Sprots exhaust was loose once again. I removed the clamp and put in two patches of 1/4 galvanized steel screen. This material is conformal and creates a good clampimg load. I expect that applying this material to one side only would be better than both sides. This is an interesting arrangement but is known to go loose and it cannot be tightened up as it designed to be size on size. If it does not fit, then you have to do things like this.
The holes in the muffler rubber hangers were quite elongated with allowed the muffler to have a free range of motion in these slots. I stuffed the free space with short lengths of VAC line to eliminate this free degree of motion. These can be secured with wire ties at each end, or by one threaded through the VAC line and wrapped about the whole affair. New rubber hangers would have been good but when things are not at hand...
So those are three or four things that one can watch for.
Note that these three repairs used bit of scrap material that I pack-rat for things like this. Anyone else have the spouse get on your case for keeping such junk around?
