摘要： A muffler for receiving exhaust gas from a combustion engine comprises a shell, first and second inlet pipes each having outlets providing exhaust gas to a mixing chamber within the shell, a first chamber and a second chamber positioned within the shell and a pair of communication pipes each including an inlet receiving exhaust gas from the mixing chamber. Each communication pipe includes an outlet providing exhaust to the second chamber. Each of the communication pipes further includes a Helmholtz opening positioned downstream of the mixing chamber. The Helmholtz openings are open to the first chamber.

摘要： An exhaust system for receiving exhaust gas from an engine of a vehicle includes first, second, and third exhaust components, and first and second pipes. The first and second exhaust components are each adapted to receive exhaust gas from the engine. The first pipe has a first inlet, and first and second outlets. The first inlet is adapted to receive exhaust gas from the first exhaust component. The second pipe has a second inlet, and third and fourth outlets. The second inlet is adapted to receive exhaust gas from the second exhaust component. The third exhaust component is disposed downstream of and laterally between the first and second exhaust components. The third exhaust component has third and fourth inlets, and fifth and sixth outlets. The third inlet is fluidly connected to the first outlet. The fourth inlet is fluidly connected to the third outlet.

摘要： A muffler for receiving exhaust gas from a combustion engine may include a shell, an inlet pipe, at least one outlet pipe, one or more baffles, and an internal communication pipe. The inlet pipe may extend through the shell. The outlet pipe may be in fluid communication with the inlet pipe and may be at least partially disposed within the shell. The baffles are disposed within the shell and cooperate with the shell to define a plurality of chambers. The internal communication pipe may be disposed entirely within the shell and may be in fluid communication with the inlet pipe. The internal communication pipe may include an inlet opening and first and outlet openings. The first outlet opening is open to and in direct fluid communication with one of the chambers. The second outlet opening is open to and in direct fluid communication with another one of the chambers.

摘要： 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.

摘要： 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.

摘要： An exhaust assembly includes first and second exhaust devices, and first, second, and third mufflers that are disposed at first, second, third, fourth, and fifth heights, respectively. The first and second heights are greater than the third, fourth, and fifth heights. The first muffler includes a first housing, first and second inlets, and first and second outlets. The first inlet receives exhaust gas from at least one of the first and second exhaust devices. The second inlet receives exhaust gas from at least one of the first and second exhaust devices. The first and second inlets and first and second outlets all fluidly connected. The second muffler includes a second housing, a third inlet that receives exhaust gas from the first outlet, and a third outlet. The third muffler includes a third housing, a fourth inlet that receives exhaust gas from the second outlet, and a fourth outlet.
