Rattle Sound

[Who_Ryder1]

Hey guys, wondering if you can help me diagnose this rattle sound. Is this a Cat Converter sound or a loose heat shield somewhere? Its been way to to to cold to look under my car and i don't want to take it to a mechanic to diagnose just yet. Its not effecting the car or the drive but its annoying.

If the noise goes away at different rpm's its the heat shield

I dont hear it when i'm driving just when the car is idling. or when going less than 5 mph. I'll get under the car tomorrow with a stick (for reach) and determine which shield it is.

I looked for a loose head shield and could not find any. i will look again tomorrow. The sounds seems to be come from the drive side areas but i can cant point point it... we turned it on and we can head it but doesnt seem to be come from the cat converter either... so, at a total loss right now.

It can be pretty hard to find the rattle. I suggest that you have someone sit in the car to rev the engine a bit while you look and listen for the rattle. You can also try tapping the exhaust pipes in a few spots to see if you can find anything loose.
