Is this a stock exhaust on an '08?

Here's a few pics of my underneath. For some reason the exhaust looks different from what I remember on my other '08. The guy in the shop today said it looks like different too, but that could be because of the air suspension...

I called my local dealer and gave them the numbers on the bottom and they didnt come up with anything and said it doesn't nessessarilly have to be a GM OEM product... I can't find anything on Google either... Can someone with an 08-09 see if they have the same one.

Stamped on it it says:

GM
