yeah cos i havent got any for mine and was thinking of doing the same to avoid the hassle if god forbid i do have a run in with the cops.

Excuse my ignorance on this matter, my only real concern i guess is if you fail to get a permit because a mod doesnt meet all legal criteria, e.g. exhaust too loud, do you have to rectify it ? like you would if you got pulled over and given a yellow sticker ?
