This is what I did, 2.5"-3". I bought an extra plate from turbonetics and gave it to the exhaust guy.
You should seriously think about getting the external wastegate while your at it. It's easy horsepower for the extra $250.
This requires a different plate from turbonetics that replaces the stock wastegate housing with a 1/2" steel plate. The only thing left to do is drill out the wastegate hole and weld in the new pipe.
I saw a dyno chart on here awhile ago that showed a 30-40 horsepower difference between the stock wastegate and external wastegate.
Check out my exhaust section to see pictures of Steve Y's downpipe and wastegate.
It's on my list of things to do when some extra money comes my way!
