If memory serves they are all 3.5 at the turbo as that is the turbo outlet hook up. Mine is anyways. Then within 1'' it immediately kicks up to 4'' the rest of the way all the way out to the back of the truck. As long as it is a stock turbo anything on those sites is correct for what your doing.
Take a closer look at your turbo and your down pipe.

Apparently memory doesn't serve, I must have been thinking of something else. It is 4'' but has a little neck/shoulder for the clamp. I dont know what I was thinking. Good catch, my bad.
