Holes in Resonators?
Lately i've been hearing a loud chirping/squealing noise coming from my exhaust at around 1500 rpms and between the speeds of 30-40mph. Its so loud that if i'm driving next to a building, I can hear it echoing off the wall of the building... It sounds terrible.
Maybe a clamp is SEVERELY loose and vibrating like crazy, but vibration noise sounds different. It's almost a screeching noise. It sounds like a very loud cricket is underneath my car. Any help is appreciated.

Those are your mufflers. That hole is normal... the resonators are the two cans BEFORE the mufflers, just ahead of the rear axle.

There have been several concerns of the baffles in the muffler coming loose and causing this type of noise. It may need a cat back. I have put several on for the noise you describe. Without hearing it it is hard to tell for sure.

The dealer gave me a brand new exhaust under warranty for the same sound you are experiencing at the same RPM.
