I just recently saw a memo that was floating around the US Forest Service regarding ‘performance exhaust systems for atv’s and dirt bikes.’ While these exhaust systems almost always have approved spark arrestors, the increased volume from them could get you into trouble on US Forest Lands and Trails. While States and Counties generally measure sound levels by decibels (db’s), the Forest Service determines if the sound of your machine (no matter how loud it is) is a nuisance or not. If people complain about the sound from your machine, you can be asked to curtail your activities. If wildlife is disturbed by the sound of your machine, you are generally asked to limit your activities in the presence of wildlife. If a law enforcement officer determines that the sound level from your exhaust is a nuisance, they can cite you.

I AM JUST THE MESSENGER. I’m not posting this message to say what you should or should not do. Rather, I’m posting it so that you’ll know that a louder (than stock) exhaust may get you attention that you don’t want. Not everyone likes atv’s and dirt bikes as much as we do, and if we do things that offend those people, their thoughts and opinions can make or break opportunities for us to ride in places.

Whether you feel that the small gain in performance is worth it or not, consider all aspects of making an exhaust change on your atv or dirt bike.
Again, I’m only the messenger! :icon_wink:
