Re: posted exhaust...
it just looks like cardboard. it's actually metal. Barely Awake cut one in half, but i can't find the thread. it's supposed to be a catalytic converter, but it's just a piece of junk in there. i tried to knock one out but it's stuck in there good.
you could just spend the extra cash and get an expansion chamber from SBP, 'cause there's not much that can be done with the stock pipe besides making your bike louder.
