so I measure the outlet of my turbo (I am goign to buy some nice silicone couplers. It is a hair over 2 in. I can get 2in or 2.25...what do you guys think? I am thinking the 2in and it could strech just a hair.

yeah, you can stretch it if you have to. If it gives you some fuss, put it in some boiling water and then go install it right afterwards.
