I believe N1 is just the style of the muffler. I notice most the time "N1" exhuast all have a oval muffler instead of a square looking oem one. Also from my experience most the N1 exhausts are all loud and sometimes raspy. I would recommend going with magnaflow for the 3.5. I have the magnflow catback and the sound is deep and not raspy what so ever.
