New Snowmobile Muffler Requirements for State of Minnesota

Minnesota Statute 84.871 governs snowmobile equipment requirements, specifically mandating that every snowmobile use an operational muffler to prevent excessive noise, prohibiting sharp popping or crackling exhaust sounds, and outlining misdemeanor penalties and fines for violations.

Key Rules and Requirements

• Working Muffler – Every snowmobile must have a working muffler in constant use to prevent loud, unusual, or excessive noise.
• No Harsh Sounds: The exhaust system cannot make a sharp popping or crackling sound, and it must blend exhaust noise into the overall machine noise.
• Race Exemptions: The noise rules do not apply to organized races or competitive events held on private land with permission or on approved public lands/water.
• After-market Parts: Replacement or after-market mufflers must feature a permanent, visible stamp showing they meet official state noise limits.
