Patent ID: 7766123

Claim:
An exhaust system, comprising: an exhaust pipe that is connectable to an engine of an associated vehicle; a silencer connected to the exhaust pipe, the silencer comprising an outer housing and an inner core extending within the outer housing, the inner core directly connected to the exhaust pipe such that exhaust gas entering the outer housing of the silencer is delivered directly into the inner core; a tail pipe connected to the silencer; and at least one conical member positioned within the silencer and including an upstream end and a downstream end, at least a portion of a side wall of the conical member being formed with a plurality of through-holes; wherein the at least one conical member is located at least partially within the inner core and oriented such that a radial dimension of the conical member increases in a direction from the upstream end toward the downstream end, and such that exhaust gas entering the silencer and traveling in a direction substantially aligned with a longitudinal axis of the inner core impinges the at least one conical member at an oblique angle; and a largest radial dimension of the at least one conical member is spaced from an inner surface of the inner core to define a gap between the at least one conical member and the inner core.
