o ya, so just to give yall some more of my thoughts, so the apexi dual n1 is the 65mm piping and most of the other exhausts are 80mm (apexi n1, greddy, hks, blitz, brm)

in the world of turbo cars, no exhausts is the ideal setup, or a huge strait pipe running from the turbine to the side of the car, however that is not practical on street use, so, in this case the bigger the better. 3.0" is a good size.you can get away with 2.5" but anything smaller and you are choking the turbine

Go 3 inch, its actually not that huge. It looks nice especially n1 style kicked out to the left. Hotness. If you want a nice cheap, GOOD quality exhaust. Go with a magan racing, off ebay. Dont let the cheap name fool you. Thats what I have, all the welds are perfect, bends are smooth. Sounds like a damn supra, and is 300 shipped. Its an exact is not a carbon copy of apexi n1.

The sweetest exhaust new for the money I've seen is the Buddy Club system that is going on zilvia's group buy forum. I can't say I'd want to drive long distances in that, but I am a loud exhaust kind of guy.

The pricing on their site is REALLY screwed up apparently, Greg has stated the BRM prices in another thread and they are MUCH better.
