I have first hand experience that loud pipes save lives. I can't count how many times a car would have cut me off (and on more than one occassion, put me on the pavement) if it weren't for the loud pipes on my Harley.....and yes, I have a can (aka muffler) on my sled too....it is not a "race" can but a "trail" can. Much lighter and takes less space than stock. And I have heard some stock mufflers that are louder than my trail can. I am all about respect for others, but I hate the government telling me what I can or cannot do to my sled, Harley, truck, boat, etc. I will maintain safety and respect for others, but Don't Tread on Me!
Don't tread on me? This is about respecting private property rights - those who allow snowmobiles to travel on their property.
