ABSTRACT:
A muffler system having the advantages of a straight pipe yet with sound abatement qualities comparable to those of a conventional muffler is provided. A substantially hollow elongated shell forms the body of the muffler and is provided with an inlet port at one end disposed in offset relationship to an outlet port at the opposite end. An exhaust pipe which is coupled with the engine extends into the hollow shell through the inlet port and terminates at a point interiorly of the hollow shell in a bevel end. The longest side of the bevel end is turned down into a gas dispersing finger point and is provided with a straight slot while the shorter side of the exhaust pipe is provided with a tapered slot extending longitudinally toward the end of the muffler so as to further facilitate dissipation of the gases. A similarly constructed outlet pipe extends into the hollow shell of the muffler through the outlet port. The outlet pipe is also provided with a bevel end having a finger projection extending downwardly from the tip of the end into the gas stream. The outlet pipe also has opposed coplanar elongated slots extending toward the outlet end of the hollow shell. In a modified form of the invention a partition disposed within the hollow shell divides the latter into a plurality of muffling chambers, with one chamber directly behind the other.
