3" to much for KA?

Back to the question, if you expect to at some point BUY an SR20DET or other turbo engine (KA-T, RB, CA, whatever), just get a 3", because then you won't have to buy another exhaust later. If you're never going to go turbo, then go ahead and try and follow all that debate up above this post.
