Well to my further research, I think the APEXi N1 Dual is 2.5inch in diameter, and I heard the APEXi N1 Single is 3inch with a 2.5inch converter that you can take off when you go turbo ?? (Not sure on that, if someone can explain for me) ....I'm staying N/A for a while so I'm gonna stick with 2.5inch hi-flow cat...
