Patent abstract
A selectively removable exhaust baffle which can be placed within an exhaust pipe to muffle the emitted sound. The removable baffle preferably includes a frame having a pair of legs joined by a spring portion. One or more transverse occluding plates are mounted on the frame. The frame is sized so that when it is pushed into the exhaust pipe it must be compressed. This compression holds the frame in place. The transverse occluding plate or plates lie against the interior wall of the exhaust pipe. The gas flow must therefore pass around the plate or plates, thereby attenuating the sound.
