Well, I got under the car today. I didn't really find much to tighten. I also didn't find anything readily available that I could use to dampen the exhaust. There looked to be a good inch of clearance at minimum around the exhaust so I'm not convinced that is the problem. It also was perfectly smooth all around so it didn't feel like it was rubbing on anything.
I took it out for a little test drive, and the sound is more of a creaking sound. It only occurs on the point where the car stops completely. I couldn't really get it to come on during acceleration. I drove over a speed bump and the front wheels didn't make any noise, but when the rear wheels went over the bump (and made it down to the other side), the creaking sound showed up there.
It definitely sounds like something is a little loose or just not solid under the car. I think I've run out of things I can do with what I have. Does anyone have any further suggestions?
