Accessories Oddness?

[DofD]

I was looking through the GM accessories for 2009's and the GMPP air intake isn't listed as an option for the 2009 Silverado or Tahoe. The GM cat-back isn't listed as an option either. They're listed for 2008's.

 

If someone know, is it that the accessories list just isn't fully updated or that those items just aren't an accessory for the 2009 models?

Are '09 models any different from 08's? Are they all finally getting the 6 speed auto transmission?

As far as I know they aren't all that different from the 08's. Though they are getting the 6 speed transmission in most models.
