1. A constant velocity muffler assembly for maintaining a constant velocity of exhaust gasses traveling through a vehicle exhaust pipe, said assembly comprising:
a muffler being fluidly coupled to an exhaust pipe of an internal combustion engine wherein said muffler is configured to facilitate exhaust gasses to pass through said muffler; and
a cylinder being disposed within said muffler, said cylinder being oriented to extend along a flow axis of said muffler with respect to the exhaust gasses wherein said cylinder is configured to deflect sound waves from the internal combustion engine thereby reducing a noise level of the internal combustion engine, said muffler swelling outwardly at a middle of said muffler to accommodate said cylinder;
wherein said muffler has a first end, a second end and an outer wall extending between said first end and said second end, each of said first end and said second end being open, said muffler being substantially hollow, said outer wall being continuously arcuate about an axis extending through said first end and said second end such that said muffler has a cylindrical shape;
wherein said outer wall has a first portion, a second portion and a third portion, said first portion extending from said first end toward said second end, said third portion extending from said second end toward said first end, said second portion extending between said first portion and said third portion;
wherein said outer wall has a pair of shoulders, each of said shoulders being positioned at an intersection between said second portion and a respective one of said first portion and said third portion; and
wherein said cylinder has a front end, a back end and an exterior wall extending between said front end and said back end, said exterior wall having a pair of sloped portions each tapering to a blunt point at a respective one of said front end and said back end, each blunt point being positioned at a transition from a respective one of said first portion and said third portion and a respective one of said shoulders.
