Abstract:
A muffler device, in one preferred embodiment, having four barriers therein. Each barrier functions to form an within which the exhaust stream can be partitioned and redirected. Eventually, the exhaust streams are once again recombined and expelled from the muffler. The partitioning and reassembly of the exhaust streams provides sound attenuation while increasing the horsepower of the engine and without resulting in any build up of unignited fuel.
