Check with any of the vendors on this board. They will be able to fix you up.

Stock:
Turbo to IC = 2" (i.d.)
IC to Uppipe = 2.5"
Uppipe to Throttle body = 2.5"

You can use big-rig coolant hose (goodyear, gates) in either rubber (black) or silicone (blue) if you don't want to shell out for/don't like the thin silicone import-ish hoses...
