I am currently running a stock 08 exhaust with a PMB tip. I would like to upgrade to a slip on in the near future, but can not decide what direction to go. I ride with a couple of buddies that run FMF Q exhaust and they are quite. Are there any other pipes out there that will give me a quite tone. On a side note, I am thinking about getting an insert for the PMB, but I would like more power!
