The long tubes will make more power, I don't think you'll be giving up much going from a dual to a single, 3.5 is big enough for gobs of power.

Re: y pipe vs. duals?
If you are really concerned go with the 4in cat back from mufflex. I am running hedmans with dual 3in going into a dual 3in in to 3in out catback and it flows very well I think. I only have a mildly built 350 though.
