If you plan to go turbo later, get the 3". It's a worth while investment. If you plan to keep NA for a long time or not to go turbo, go with the 2.25 to 2.5. If that's the case, you can have a look at Blitz Realize TT or Greddy's SP. If you like the N1 styling, have a look at the HKS Hi-Power for the 240sx, not for the silvias. Those use a 65mm pipe versus 80mm for the silvias.
Also, the engines for the 240sx don't really matter as long as you're running SR or KA, it shouldn't change the location of anything so you should have no fear with the type of exhaust you're getting as long as it's for a 240sx.
