Today I removed the two heat sheilds over the cat converters on my 98 328i today. They were rattling and I couldnt stand the noise any longer it was driving me nuts, especially when the windows were down while going over any bumps.
I hope that this wont cause any problems with them not being there anymore...heat issues, or anything else I might not be considering.

Has anyone else done this, or have any input.

Its generally not a problem unless you get some road debris up under there and it catches fire. There's a insolation ring at the front and rear of the heat shield and they break up and fall away, leaving the heat shield lose and rattling. I took mine to Midas and had them tac weld the shield back down a few months ago, so far so good. On another car that did it I stuffed some JB Weld in there and it held fine, no rattles. But keep a fire extinguisher in your car just in case.
I've replaced my rear shock mounts recently, but when they go bad I'd describe it as more of a clunking than a rattling. So depending on the noise it might not be that. Of course I couldn't get an objective analysis on the noise until I took all the debris from my trunk. It goes in all organized, and somehow always comes out all beat up .

I hate that. I destroyed a perfectly good CD-changer because of a large heavy flying object in the trunk when I slid a corner. Oops. That was kind of an expensive corner.

Above the entire under car exhaust is like a heat shield padding so there shouldn't be any problem, unless like Hamfisted says if something catches fire.
