blown applications get the largest header possible in my camp. "possible" meaning budget or availability.

1-7/8" for sure

How about this question
Which y-pipe would be best ? a Kooks/ARH style or a custom with a Flowmaster merge ?

Think there is any difference in the 800rwhp range ?

Go with 1 7/8 minimum as said. I've got kooks 1 7/8 with kooks Y and 3" cutout about 18" after. I picked up 80rwhp by opening the cutout. Wish I would have went 2" with 3.5" Y into 4" exhaust.
