Noise does not make pilots faster, but makes locals angry. Therefore and to decrease the environmental impact caused by this event, since 2 years loud exhausts, like aftermarket (sport) exhausts have been banned by our rules. 2017 will be the very last year in which such aftermarket exhausts are tolerated IF equipped with silencers. If you don’t want to put the original exhaust on your vehicle, or a silencer inside, please do not come. Lets be happy that CFMOTO-HUNT-THE-WOLF remains an event with very few rules. And to keep it like this, stick to the few given! No silencer = no start = fun and money lost.
