I'll give ya the 411 on the Tanabe super racing medallion. I put one on my 5th gen lude, and god damn that thing is loud. I'm sure that if I was pulled over and had to do a sound test, i would pass miserably. BTW, i dont run with my silencer in haha. with the silencer in, you can barely hear it. I mean the silencer works that well, but when its out, I set off car alarms just driving down the street. Not too sure about the N1, although I've heard that is loud also. Just to let you know also, I've driven by Numerious (prolly 50) cops since I've put my exhaust on and so far I have not been pulled over. all you gotta do is go light on the accelerator and not punch it. Also, might want to switch gears lower, like around 2500 to keep the noise down. Good luck! =]
