I put the EVO on my 850 and it did give it more power and sounded cool.
Even with the quiet insert and spark arrestor it is loud.
I only used it one time and went back to the stock exhaust because I ride in a national forest with hikers and horseman and don't want to give them any more fuel to close down more trails.
I now have the Scrambler 1000 and I'm pretty sure the dual exhaust is just a little quieter.
I posted that the Big Gun Evo exhaust was really loud with the quiet insert,
looked inside it today and it only has the spark arrestor. It was suppose to come with the quiet insert, no wonder it was so loud!
It did sound really cool
