Well guys,here in Ontario,the police have been checking for aftermarket pipes and writing fines for a few years now. I have heard of guys coming up from the states and being refused entry due to "race" pipes. Its not the 100 that go by that piss people off,its the friggin moron with straight stingers at 3 in the morning coming home from a bar that get land owners pissed off. Doubt it? Try sleeping in your cottage 1000 feet from a main trail when one of these suckers is coming. You hear them for 20 minutes coming and going. Remember,cold dense air carries sound real far. I am not against loud pipes as per say,just irresponsible use of said "race" pipes by trail riders. With most modern sleds capable of running over 100mph bone stock,is there really a need for super loud pipes to gain 2 or 3 mph? Most of the manufacturers of aftermarket pipes are working really hard to make quiet performance pipes but untill they do,fines will be written and more land owners will close the door to their property as a result of a few selfish individuals. Sounds kinda like boating doesn't it?
