You should be fine without them. Do you need them for inspection? Technically yes. Just don't got to cole muffler, or monro or a place like that. Those guys think they need to look over every car with a fine tooth comb and take an hour to inspect a vehicle. Go to a mom and pops garage and get it inspected. A lot of them will roll the car in, look at it a little bit and slap a sticker on it and you are ready to go.
