If you can tell the difference between a 2.5-inch and 3-inch exhaust on a mildly modified turbo car making 200 hp, I will fly to your home and give you a brand new, shiny nickel.
:-)
3-inch is more expensive, tougher to fit, and, if you're using a stock cat, limited by the cat's narrower diameter.
The tube diameter isn't important for your car. What is important is that you get rid of the stock cast-iron 90* exhaust elbow. ASSuming your 90 has the original Mitsubishi turbo, go to eBay, search "TE05" (that's a zero, not the letter "o") and buy a flange. Bring it to your exhaust guy and have him weld a "bell mouth" piece over it so that both the exh and wastegate holes are enclosed in an ovalized tube. At images.google.com if you search "bell mouth" exhaust you should find pics of what I'm talking about.
If you have a T3 turbo from an earlier car, post back and I'll give you more free advice from a stranger (trust me, though, it's good advice). :-)
PS I know of a Honda Civic that makes 400hp at the wheels with a 2.5-inch exhaust...
