IC and test pipe, or down pipe, you'll notice the limitations of the stock IC more when summer hits.. for the money, there's not as much gain from the exhaust if you're going to keep the stock turbo frame.. You'd be better off spending the dough on injectors and e85 or most any other perf mod before buying a pricy exhaust. If you can find a decent used one, then it's a better investment.
You can modify the stock exhaust for some minimal gains and volume. But, for the modified stock turbo you mentioned, I'd look into getting a 2.5" custom setup, over the standard 3" stuff most guys buy, Mostly just for cost and volume reasons, otherwise 3" should work fine.
