I purchased the exhaust combo for my son's KX85 and he loves it. The bike sounds better, looks better and runs faster. I would definately do it all over again if I had to. We have bought several products from MotoSport and have been happy with them all. The selection and availability is outstanding, plus you can't beat the shipping cost and you get it super fast. I now don't even bother shopping around, I just go straight to the Moto Sport web site and get what I need.
