But basically from some research, I found that the STI crossmember sits about 7/8" higher than the 5-speed, which would make sense why this DP isn't fitting as it needs just about a 1/2" of clearance to fit.

The turbo, exhaust manifold, and uppipe are all seated properly, as I was able to install all of that on the engine stand before dropping it in the car, and the turbo is properly bolted down.

Either way, looking to have this issue solved soon, whether it involves cutting up the DP to make it fit, or just a good ole heat-n-beat method.
I was going to comment on this right away but I decided to go back and find the context of the original situation. I was going to mention that my modified twinscroll flanged MRT catted downpipe did not fit either due to the gear box as well. My issue however was that my downpipe fit in the 5 speed but when I did the 6 speed swap, the tranny was much larger and wider that the clearance for the cat was no longer present. I ended up with a JDM AVO catless downpipe. (wow, that was more writing than I anticipated)

In regard to Scoobystas' situation, you could probably use the crossmembers from the 05-07 wrx's as a cheaper solution to your issue. They are identical to the 05-07 STi crossmembers since they share the same steering rack. I know that it has 6 mounting bolts instead of the 4 mounting point that 04 and below share but you can use just the 4. It is not any less secure because that is how our crossmembers are mounted. The other 2 holes are for hindering lateral movement on the newer racks. I hope that helps
