摘要: A dual mode exhaust muffler for the engine of a vehicle that may be shifted between a quiet mode and a loud mode. A single muffler, a dual transverse muffler with two independent exhaust flow streams, and a dual transverse muffler with a combined exhaust flow stream embodiments are disclosed. An inlet tube may be a solid wall tube to minimize sound attenuation in the loud mode. The dual transverse muffler embodiments utilize an exhaust flow path that passes out through a reticulated wall of one tube and passes into a reticulated wall of a second tube. A vacuum switch having a two position on/off slide actuator may be used with any of the muffler assemblies.
