You are going to want 3" true duals to really let that motor breath. Any other Y pipe to a catback will probably be to restricting for that engine ..
Good luck and I wanna see some pics of the engine/motor/finished product

not really...2.5" would probably suffice. i doubt you'd see much of a restriction between the 2. maybe if you're breaking the 550 ro 600hp level.
here is some basic math for those interested:
cross sectional area...ie...flow potential:
dual 2.5" pipe = 9.8sq in
3" single pipe = 7.1 sq in
dual 3" = 14.1 sq in
single 3.5" pipe = 9.6 sq in
single 4" pipe = 12.6 sq in
