TSB 08-2-10 question
I reached out on your post on a different forum, but please PM me your VIN (on either forum) so I can review your situation. Talk to you soon.

It was the exhaust mounts for the H pipe.
I ordered a new seperator plate and replaced it myself. I thought for sure that was the problem. There was even a shinny spot on the old plate right where the new plate had the cut out. But sure enough, I hear it as soon as I start it up. In fact it got worse, which made it easy to identify as the H-pipe exhaust hangers. I initially suspected the hangers and got under the car and hit them with a dead blow hammer but never heard anything. I guess since I had H pipe out to swap the plates I must have move it just enough to make it worse. After still hearing the noise after installing the new plate, I hit them again and it was clear that they were making all the noise. Even thought the exhaust hangers were perfectly centered inside the rubber isolators, the metal c-clamp would vibrate against the cross member at certain frequencies.
Removed the hangers and problem solved.
