Ic Pipe size 2 2.5 or 3"?

[s2dk]

Hello

I was wondering What whould be the optimal size to go with
Im on a gtx3076 gen 2 ar 0.82
Outlet of turbo is 2"
Was thinking to go 2.5 to ic (600x300x76 vore with 3" in/out) and the. 3" from ic to tb
Tb wil be Stock or 70 mm one
Could i just gi 2.5 all the Way or What Do you Guys Do?
I whould Think that the 2.5/3" would be most optimal?
Maybe a 2"ic -2.5" tb ?
Regarding core i Could Allso go with a 2.5" in and out?

Bring the science and make me smarter 😜
