1998 Z28 A4 Noise, Please help! Today when I got off work I turned my car on and let it warm up for a couple minutes. Before I left I revved it a bit not even exceeding 2500 RPMs and I heard like a rattling noise when the RPMs started to come down. I drove home and didnt hear the noise while cruising so after 10 minutes of driving I pulled over and revved it a bit in Park and Neutral hoping it wouldn't sound and unfortunately it did. I checked all of my fluids and they seem to be at good levels. My transmission oil level is good but it isn't red. I'm guessing I need a change soon.
I also put some rags in my tailpipes thinking it was an exhaust leak but it sounds the same. Car only has 30k original miles. I will be posting a video so that you guys hear for yourselves and hopefully are able to tell me what the problem is.

Get under the car and bang on the catalytic converters with a rubber mallet and see if it rattles. I'd be willing to bet that you had some material in the cat break loose and it's rattling around in there. This is very common and thats exactly what yours sounds like.
