iv read the tread on the micron and im very impressed by the numbers, but i am wondering what would be the best sounding and performance increasing exhaust on the market for the XB9. Iv seen that many people have been running the Jardin slip ons which sound great but im not sure on the power numbers? SO has anyone out there put any exhaust on a XB9 and what was your experiance with it....did you feel a difference, how does it sound...ect. thanks, mike
