Loud equals pissed off home owners who allow snowmobilers through the property they own on the trail. Loud equals tickets from your local DNR and trust me they are cracking down all over the country on snowmobiles for loud. There is a decibel limit on trails. We lost a big portion of a trail because of people with loud exhausts after years of warnings and finally the owner had enough and shut out DNR from putting a trail through his property. So think of others when riding, the home owners who allow trails through their property. Loud is not good on trails or off trail.
