meh, who cares man, everything is illegal nowadays, if you get caught just take it and pay the fines. i mean youve gota bigger chance of getting caught if you had a huge exhaust that was loud as or you drove like a dick. like i said before i to drive a 33 gtst 'high powered' but every mod im planning to do il do sensible for example turbo back exasust 3 inch tip, quieter. painting my cooler black, every lil bit you do helps.
If you drive under the speed limit, not rip other cars of the lights, not go sideways on main roads etc etc youl have a much LESS chance of getting pulled over
