Depending on where you live...We have emissions testing. So becareful with the O/R X pipe and inspection time.
Front plates is a must unless you like Johnny Law.
99% of the time, front plate ticket is a fix it ticket. I got one, slapped the plate on the car, took a picture of it and showed it to the judge. Paid $30 for court fee's and the judge dis missed the ticket. If the judge or cop wants to be a dick, then a front plate ticket is around $200 if im not mistaken.
Living in a smaller city like Waco, they don't mess with us when it comes to front plate. No sniffer test either. As long as your lights, horn, and windshield wipers work you are good to go.
