Just wanted to give a little update about the yosh exhaust now that I have gone on several rides with it and the k&n filter installed. So when I first put the pipe on I was obviously hot rodding like crazy so of course it seemed extremely to loud to the point I was ready to take it off. I did add more stainless mesh the pipe to try and help and it did help but only a little. So the last couple of rides I've gone on have been with other people. Took my wife and my 6 month old son for a couple of rides. And when just cruising which is normal for trail riding the exhaust is very tolerable. Don't have to turn up the stereo any louder than before which isn't that loud. The nicest thing about it is when cruising and a small hill or hill climb comes up the worry of not being able to make it or if having to stop on a hill then give it some gas the pioneer just jumps and goes now. Before it seemed like the pioneer would struggle to go up not anymore. I will say once my son can sit in the back by himself I will still put ear plugs and a helmet on him or muffs. I am actually really glad I have it because is has made a difference in power because I was ready to take that thing off and sell it.
