no clue what an N1 sounds like, and I didn't get a chance to do it yet. My dad was going to give me a hand, but he's slacking. So it goes in tomorrow morning. At least I really hope it does, I want it in before the track day at Laguna Seca on Saturday.
oh, I know that BRN2RLY has an Apex'i N1, and I'm supposed to meet him one of these days, so I'll compare my exhaust to his (when I do meet him) and get back to you on the sound.
