How you take the baffles out of a Honda shadow vlx 600 2006?

My bike & many others have made the Mod known as "Hole Saw". It is simple. you put a dowel or something in the pipe for the mandrel's centering bit in a hole saw to drill into. Then saw the hole & remove aft baffels. The forward baffle (still there), makes the bike quieter than anti social straight pipes, but now it will sound like a cruiser. Mark
