I only have an N1, but later this week I'll have my Nameless Front/Overpipe, I'm excited to see how it sounds.
I've put well over 30k on the N1, so far I don't mind the noise; in fact, in may be a little too quiet for my tastes. I like loud. Whenever I'm around cops, I just baby the car and am fine. Hell, if my friend with an STi can run a catless front pipe and an N1 and never get pulled over once driving through LA, I'm pretty sure we'll be okay
