Right after the Y merge (the upper left of the picture you can see a little bit of the weld, that's the merge), it jumps up and over the Tcase crossmember, then right into the converter. It's a pretty good ways away from the manifolds, and apparently GM thought it was good enough?

Cat inlet just about even with the end of the T-case on mine, not sure the length difference between the TH400 and your setup.
