What is your question?

when I start the car and take off I heard a rattling noise. I took it to a mechanic and he says that is my tailpipe. Is the tailpipe loose or not, I dont know if I need a new one or what. He didnt say, kept talking about I need a tune up. What has that got to do with a tailpipe? So I really need your help if you can.

What makes this problem better or worse?

it's a little loud when the engine is cold, once warmed only noise when I back up or pull off

How long has your 1997 Chevrolet Lumina had this problem?
