im under the new laws too with my n/a.. havnt been pulled up yet then again mine doesnt make any noticeable noise.. cant hear it at all tbh i duno why, its a K & N pod too btw, could just be because the extractors and exhaust is making a bit of a noise and cancels it out.
from most people i have asked they say its ok to have 1 on a n/a, the cop would have to be a tight ass and if you act dumb / nice to the cop i dont think you will get done 3 points for having it on.
