Hrmm.
I got a list for fmic, blow off, exhaust etc and the guys didnt even touch my car, just bent down to make sure there was a front mount... Problem is, permits or not, cops will still sticker u if they think anything on ur car looks dodgy. Or if they dont like you. Or if u are a smartass.
In summary, u will get a sticker if the officer who pulls you over wants to give you one.
