370z exhaust weird noise
 

Hey guys, I need some help pin pointing where this noise is coming from. I'm like 99% positive that its coming from exhaust but I am not sure what part. I've been wanting to get under the car and take a look but I just haven't had the chance. It usually makes this noise in the 2k rpm range. Any one have any suggestions why my car is making this weird noise?sounds weird like a high frequency

The answer is in his thread I think.
