摘要
An automotive muffler having a device for switching between loud and quieter modes includes a chamber having an inlet exhaust pipe and an outlet exhaust pipe for the passage of exhaust gases through the chamber. The first section of the chamber has a plurality of baffles with openings through the baffles for the passage of the exhaust gases. A second section of the chamber, separated from the first section of the chamber, permits a substantially unobstructed passage of exhaust gases through the second section of the chamber to the outlet exhaust pipe. A switching device is able to be selectively switched between diverting incoming exhaust gases substantially through only the first section of the chamber and diverting incoming exhaust gases substantially though only the second section of the chamber, so that when the exhaust gases are substantially diverted through only the first section of the chamber having the baffles, the automotive muffler is operated in a quiet mode and when the exhaust gases are substantially diverted through only the second section of the chamber, the automotive muffler is operated in a loud mode.
