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.


1. A muffler device, comprising:an enclosure having an inlet conduit through which exhaust gases are received within said enclosure, and an outlet conduit through which said exhaust gases are expelled from the enclosure; a first barrier located within said enclosure and proximal to said inlet conduit such that a first compartment is formed between said first barrier and an inlet wall of said enclosure; a first aperture and a second aperture being defined through said first barrier, whereby said exhaust gases are split into two streams; a second barrier i...
