Diameter of stock up pipe?

[turbov6joe]

What's the diameter of the stock up pipe from the IC to the plenum? What is the diameter of the Duttweiler neck modifcation for the stock IC and the outlet size of a TE44? I really don't want to yank mine off to measure, so I'm hoping that someone knows this off the cuff. TIA

2.5" for the up pipe and the Dutt neck is also 2.5" Outlet of turbo is 2"
