gibson exhaust question

[Nicholas DeMarco 2]

trying to find a gibson exhaust for my 05 4x4 and for some reason it's only coming up for 2wd for 05 but for 01-04 it's for both 2wd/4wd. anyone with a 05 4wd get a gibson and have problems?

'01 to '05 is all the same, Im sure. The magna-flow cat back is.
