First off, Love this forum!!! I am new here and I am ready to "Exhaust UP" on my 2002 660 and obviously jet up as well. My bike is all stock with the exception of a K&N filter. Can anyone suggest a good set up for me on an exhaust system? I was looking at the Big Guns, but not sold on it yet. I am primarily looking for a mid range increase for those dunes out at Glamis. Any and all suggestions would be greatly appreciated.
