Many snowmobile racing enthusiasts believe removing their mufflers, running straight pipes and retuning their carbs or fuel injectors will give them a much quicker sled.  This may be true, but because you just voided the manufacturer's warranty by making these alterations often leads to a much quiker engine failure !  Unless you are sponsored by many snowmobile manufacturers, dealers or accessories vendors for Pro & Pro-Am Competitive Events, it will set you back about 3 or 4 thousand dollars just to get it running again. To get these sponsorships you must be Pro or Pro-Am registered. Contact NYSSA to find out about the different racing programs available to you. If you don't, then at least contact NYSSA to find a LEGAL Area in which you can run your Racers, because it is Illegal to ride on trails & trespass on private properties or public lands throughout N.Y. State. Law Enforcement will eventually find these sleds and have the authority to confiscate and impound these alterd sleds once they have been reported by a citizen of the extreme loudness and noise it caused. If this conduct continues, it could be considered harrassment and the owner could be fined !  So please take your Racers to a facility that supports these alterations and create a better relationship with your Neighbors and Snowmobile Clubs. Don't jeopardize the sport and recreation of Snowmobiling for a quick thrill ! We have been receiving many complaints this season of the unbearable noise from the altered sleds by Land Owners.  On Sunday, 1/30,  there was a group of sleds behind the E. Berne Mobil-Mart where they gassed up and then headed toward Knox running through hedge rows and damaging the trail system.  Inspect your sled before riding and ensure you and your sled are 100% LEGAL.  REMEMBER, THERE ARE ABSOLUTELY NO  SNOWMOBILES  With  ALTERED EXHAUST SYSTEMS ALLOWED  To RIDE On ANY TRAILS  IN THE STATE Of  N.Y. !
