Is the N1 dual or the single better? I like the look of the dual but I want performance to be my first concern. Also what is the difference in HP gain between the 5-Zigen and the Apexi N1 series? I know that the Apexi has like 3.5 inch
piping, is that for N/A or is that the turbo version? I know that some amount of back-pressure is a good thing and that is why the 2.5 inch 5-Zigen system seems better. But you guys would know better than I would and that is why I am asking. Thanks for any help or advice you guys can give.
