I am a life long snowmobiler and absolutely love the sport. I am also a land owner that gives permission for club trails to go over my land and I also have other trails that go within 1/8 mile of my house. Loud pipes at 1am on open trails have no place in this sport in my opinion. If you use them to run lakes during the day, that's another story. My neighbors say "they hate those snowmobiles"...they mean they hate the couple of boneheads that wake them up running loud pipes in the middle of the night. We all get bad names from it...Marc
