I just thought I would post a reply of what they did. The tech took off the old timing set and just by looking at it it looked fine. With the new one one, I cant hear that knocking/rattling noise any more.
Oh, while he had it torn down, I let him install my GMPP exhaust manifold for me.(free of course

i have had this same problem scince day one. It only does it while it is warming up and then it goes away. I took it to the dealer and they said this is normal for my car lol!! So i dont know what to do. The car runs fine but i hate that sound every morning.

is there a TSB number on this? I tryed taking it to the dealership but they wont do anything because of the motormounts and transmounts. Will GM give the information to me or does a dealership have to call?

Mine was made 4/16/06 and has been making that sound since 3k on the od...
here is a vid, you cant really hear it thanks to the wind and CAB mod but when I am looking down at the stock header it seems loudest: http://s127.photobucket.com/albums/p...Walkaround.flv

The bad thing is it fixed mine for a little while. Now it's doin it again. Same sound but not as loud.
GM has no idea on what it is. And since it's only every now and then and not all the time, they can't/ wont do much about it.

HaHa, do you know what I just thought of reading this. Maybe Mr. Andy Wise of the Memphis ABC news should read this and see what do when you actually, sincerely find a TSB no one knows about and want to help.
I think I might have this, I may say something when I take her in for inspection this weekend.

Yours is just before the dates on the TSB. Your build date is 3/21/06. Yours does have a recall/bulletin on your exhaust. If you ever had a SEL and a code P0420 you might can get your cat changed out
