Why does my Audi 80 make a strange noise when I accelerate?

I've noticed that when I accelerate, my Audi 80 makes a weird rattling noise. It goes away once I reach a higher speed, but it's really bothering me. Any idea what could be causing this?

It sounds like you may have a problem with your exhaust system. Have you noticed any changes in the way your car drives or handles? It's best to have it checked out by a mechanic to prevent any further damage.
