Exhaust system after the swap

Exhaust system after the swap
Right now I have the 3.4L swap running through the stock 3.4l crossover into the driver's side dump from ORS. From here I have a small piece of pipe from the stock T100 that I had cut and rotated so that the o2 sensor could be plumbed in without hitting the frame rail. From here I had someone weld the stock exhaust system to this pipe. When this was done I realized that the T100 pipe was probably 2.25 or 2.50 inches in diameter the stock pipe was at least .25 an inch in diameter smaller.
What I'm worried about is if the stock 3.0L had trouble breathing through this exhaust pipe, how much more of a difficult time is the 3.4L having. I realize that most of the exhaust restriction is due to the terrible header design on the driver's side, but how much of the restriction is also due to the exhaust system.
What has everyone else done?

I think the main issue on the 3.0 was how it was combined by just looping it and cut a hole on the bottom for exit......
The 3.4 is much better already. I took my truck to the muffler shop and have them put all new stuff in ...I kept the muffler though. I don't know what diameter they use but it meet the CA ref. standard.

I'm just wondering if I should consider getting an exhaust done after the swap, and if I should consider getting everything including the cat done, or just run a cat back exhaust. I can't imagine the stock 3.0l exhaust being great for the 3.4l, but at the same time without an aftermarket option I've had bad experiences with custom work in the past.

I'm not in California right now so technically the sky's the limit at this point.
I'm just wondering what everyone else did, I'm thinking towards a cat back exhaust but then the former engineering student in me thinks of the neck down from 2.5 to 2.25ish or smaller for the stock piping.
