My car is making a rattling noise when idle and when I start it. It goes away when I’m driving though. Here’s how it sounds: https://www.youtube.com/watch?v=9lV_ekxbGwU
That’s a loose heat shield somewhere along the exhaust system.
To fix you get under there, tap and poke to find the loose piece.
Then use a sheet metal screw or even a piece of wire or coat hanger to hold it in place.
With a little improvisation this will cost no more than a little time.
I advise against removing any heat shields. They put them there for a reason.

However, I think it is important to note that circuitsmith’s advice should only be acted-upon when the exhaust system is stone cold.

How much do you think a shop would charge?
Had a broken clamp, making a rattling noise like that, my regular guys said no charge, bender shop welded a split cat for $10, along with exhaust system, My guess $50 max and probably less at an independent shop if it is exhaust related simple fix.

Sounds exactly like my travel alarm!
Most shops today charge a minimum one hour diagnostic charge. Often with a loose exhaust part that only needs a clamp, they’ll only charge for the labor, sometimes only a nominal fee.
Thanks for the video, however. I wish more posters would take the few minutes to give us real detail. It really helps.

Do you still have the rattle or is it fixed ?

Update! It was the catalytic converter! I got it fixed on Saturday.
