I know for sure that the DP is 2.25" .

I'm not sure about the up-pipe but I think it is around the same.

The up-pipe along with the manifold is noticably narrower in diamater. I would guess 1.5 inches, but thats just a guess.

I would have to agree, my 93 turbo is about 1.5-1.75 on the up-pipe and the downpipe is around 2.25-2.5. I am pretty sure the header pipe and up-pipe are less than 2''
