    Abstract: A muffler may include a shell, first and second baffles, an inlet pipe, first and second outlet pipes, and a communication pipe. The first and second baffles cooperate with the shell to define first, second and third chambers. The first inlet pipe may extend through the shell and may provide exhaust gas to at least one of the first and second chambers. Exhaust gas in the first chamber exits the muffler through the first outlet pipe. Exhaust gas in the second chamber exits the muffler through the second outlet pipe. The communication pipe may include first, second and third openings. The first opening is in communication with the first chamber. The second opening is in communication with the second chamber. The third opening is in communication with the third chamber. The first and second chambers may be in communication with the third chamber through the communication pipe.

    Abstract: A muffler assembly includes first, second, and third mufflers. The first muffler includes a first housing and an X-pipe that is at least partially disposed within the first housing. The X-pipe has first and second inlets and first and second outlets that are all fluidly connected to one another. The first and second inlets receive exhaust gas from the engine. The second muffler includes a second housing and a first Y-pipe that is at least partially disposed therein. The first Y-pipe has a third inlet that receives exhaust gas from the first outlet, and third and fourth outlets. The third muffler includes a third housing and a second Y-pipe that is at least partially disposed therein. The second Y-pipe has a fourth inlet that receives exhaust gas from the second outlet, and fifth and sixth outlets. The first, second, and third housings are spaced apart from one another.
