摘要： A muffler for an internal combustion engine exhaust system includes a housing having an inlet and outlet headers enclosing opposite ends of an outer shell. A partition divides a housing interior into first and second chambers, the first chamber having sound absorbing material positioned therein. The partition has an aperture allowing fluid communication between the first and second chambers. A through pipe extends through the inlet and outlet headers and the partition and has a plurality of perforations enabling fluid communication between the through pipe and the first chamber. A valve assembly has a valve flap positioned inside the through pipe for rotation with an axle pivotally coupled to the pipe between a closed position and an open position. The valve is positioned downstream of the pipe perforations such that all of an exhaust gas flowing through the muffler passes through the valve regardless of the valve flap position.
