    I was pissing and moaning to the mechanic about the exhaust on my Pete. It is a stock muffler, it is just louder than normal. Anyway he told me it was supposed to be that way because it was a flow master exhaust. I fell out...:biggrin_25523:

    Yeah, it has a muffler down below now. The dynafex is alot smaller than the oem, the out pipe comes off the body. It looks alot like mufflers i've seen on internationals. I like it, it still has a good bark to it without the steady drone at highway speeds.
