intercooler piping, 2.5 in

Hey, I'm trying to upgrade all of my intercooler piping to 2.5 inch, but I don't want to use reducers on the TB elbow or the turbo outlet. It's easy enough to find aftermarket TB elbows, but I cant find a 2.5 inch turbo outlet. Anybody know where to get one?

If not, how should I run my piping so there's not a massive reducer coming straight off the turbo right next to the exhaust?

You will need to use some sort of reducer on either end...they make silicone coupler reducers, although a longer transition would be helpful on the throttle body side. You'd want to look for concentric tubing reducers in that case and weld to your 2 1/2" tube. Don't forget to put a bead on the exit end, or else risk not sealing or even holding it on (i.e. pop off) under pressure (boost).
