Abstract:
1. A vehicle exhaust assembly for modifying a sound of the vehicle exhaust, said assembly comprising: a housing operationally coupled to a vehicle exhaust pipe on the vehicle such that the vehicle exhaust is directed into said housing; a baffle coupled to said housing such that a flow of the vehicle exhaust passes over said baffle; said baffle having a plurality of exhaust apertures extending therethrough such that the flow of the vehicle exhaust passes through said plurality of exhaust apertures, said plurality of exhaust apertures altering a resonant frequency of the flow of the vehicle exhaust such that an audible sound of the flow vehicle exhaust is modified, said baffle having a plurality of cuts extending between a first lateral side and a second lateral side of said baffle such that said plurality of cuts is evenly spaced apart and distributed between a top side and a bottom side of said baffle, said baffle being divided into a plurality of sections, said plurality of cuts each extending between an associated pair of a plurality of rows of said exhaust apertures such that each of said plurality of rows of said exhaust apertures is positioned proximate and being coextensive with a bounding edge of each of said plurality of sections of said baffle; and a knob operationally coupled to said housing, said knob being operationally coupled to said baffle such that said knob moves said baffle, a user selectively moving said knob having said baffle being positioned at a selected angle with respect to the flow of the vehicle exhaust such that the audible sound of the flow of the vehicle sound is adjusted between a minimum and a maximum resonant frequency.
