I go a couple times a year, The noise check is hit or miss. Some weekends they check everyone some weekends they don't check anybody. Make sure you have sparkies they will check for those. They have a long stick they will put in your exhaust. Put your orv sticker where they can see it that will stop them from stopping you to look for it and any other problems they feel like starting.
One more thing STAY OFF the THROTTLE when you are pulling up to the check station. That is one thing that will help you not get stopped.
