high pitch noise at idle

[CoryM]

Hard to tell much from the video. Try hitting the exhaust with your hand or a soft mallet. See if you get any rattles. Also while cold, take your finger and pull on the manifold heat shield etc and try to "twang" it like a guitar string to get a noise. Often the best way to find loose heat shields. Just watch for sharp edges.

Other things that come to mind:
-cracked exhaust
-plugged cat or broken baffle in muffler causing intermittent plugging (but would expect to notice this driving, not at idle)

Any other engine problems with the car? Is it stock?

Yes, it is stock, the only difference is a straight pipe axle-back , I will try to check for a heat shield when i get home tonight after work, as for cracked exhaust my exhaust headers are RUSTED worse than i ever could've imagined so it might be leaking
