I get an annoying rattle coming from the engine bay at like 2 grand to about 4 grand in any gear, even neutral. I'm thinking it's a loose heat sheild or something because there is no performance loss, just a sound. My question is is there any other places where there are heat sheilds or anything like that besides on the exhaust mani or the downpipe? What else could be rattling or loose in there?

Also, would it be bad to take off all of the heat shields if I can't narrow down the problem?

Thanks guys.

That's the rpm range my heatshield rattled (because it was cracked) before I removed it and put header wrap on the exahust manifold.

I have the same thing, but I think it is coming from one of the pulleys. Anyone know what this is?
