Video of exhaust does not even come close to telling the story.
When you are riding the machine they are loud, when the machine is going by say for a vid they are not as bad. The problem is you are the one on the machine riding it.
I will tell you the quieter it is, the better and more enjoyable riding it all day is. Why would you even want an exhaust when you have stock muffler tunes up to 270 HP? Loud exhaust is exhausting and will wear on you if you like actual trail riding. If they are run in the deep snow it will be acceptable as the snow helps quiet the noise a bunch.
