Abstract:
An apparatus for facilitating exhaust flow to reduce back pressure in an internal combustion engine, comprising:a first non-apertured longitudinally extending conduit having a continuous cross-sectional configuration, having a proximal end for receiving pulsating exhaust of an internal combustion engine, and a distal end; and a second non-apertured conduit co-axially aligned with the first conduit, including a first segment of continuous cross-sectional configuration surrounding the distal end of the first conduit, the first segment defining a greatest cross-sectional area of the second conduit, and a second segment extending from the first segment and defining a tapered portion that connects to an exterior surface of the first conduit between the proximal and distal ends thereof in a sealed and fixed relationship therewith.
