There are 2 different configurations, the change happened on or about 5/08 on the manual transmission and was always present on DCT:

SOP-5/08 6MT - Configuration 1
6/08+ 6MT, including all DCT models - configuration 2

Belt routing:

2008-5/08 6SPD models (non DCT) belt routing


6/08+ and all DCT belt routing


Hope this helps, pulleys provide great (and inexpensive) hp gains.
