    Wait...you have the Loudmouth right?
    Why are you asking about the stock piping?

    3" catback fit on the y-pipe if that helps.

    Loudmouth is the same size as stock piping right? I just need to know what I size inlet/outlet I need. I like the loudmouth/mac mids/ory, but it is just stupid loud. Gotta grow up sometime as much as I hate to
