I just removed the first baffle.I drilled around the rear plate with a small drill bit,then went back with a much bigger bit and that made the holes intersect each other and then i took a wooden dowel and knocked it out. it left some little jagged edges in there you can grind out with a drimmel or just leave it cause unless you get down and look in the pipe its really hard to tell.the sound is not loud,it just gives the pipes a low rumble.pretty cool actually.
