I'm doing twin 61mm With 63 exhaust housing on t3 with 3" down pipes. Here is a link to my set-up. 67 chevy build - PerformanceTrucks.net Forums

Another thing that I have thought of that kinda puts twins over single is tuning. With twins you can run your stock o2's with true stft and ltft. Where as on the single the right bank gets fed both sides of the exhaust and can't truely adjust as it needs to. Granted mine afr's are usually right where I want them but the winter time things are different from summer. Iat sensor or not the air is different not just colder.

Then you have a true left/right side.

When one side of the engine feeds into the other side, there are no other ways to have a true left and right side.
HOWEVER, we've installed many of your kits Trick, in the past, and when the o2's are properly placed they satisfy the PCM.
One in the driver's side stock location and the passenger in the downpipe.
PCM doesn't really know the difference.
Just comes in handy having and left and right side when determining which bank is lean.
