I looked into the tips with a flashlight and the curvature of the pipes would not allow a straight shot with a drill bit extention. I have no idea how that guy did what he said he did! Oh well...
You know the J. C. Whitney car parts catalog? Many years ago, I saw an adapter in ther for a car's exhaust pipe. The adapter was to be inserted somewhere on the exhaust pipe, between the O-ring asbestos manifold gasket, and the muffler. The gadget had a flap on it, controlled by a steel cable, like what you'd use for a manual choke. By operating the cable, you could open and close a flapper, thus diverting the exhaust out, ahead of the muffler.
I imagine it was pretty loud. Also was a bit more elegant than using a drill bit.
