    摘要: A passive valve assembly for an exhaust system is mounted within an exhaust tube. The exhaust tube has a bore that defines an exhaust flow path having a cross-sectional area. One end of the exhaust tube is to be connected to a first exhaust component and a second end of the exhaust tube is to be connected to a second exhaust component such that the exhaust tube forms a sole exhaust path between the first and the second exhaust components. The passive valve assembly includes a vane that is mounted within the bore, and which is moveable between an open position and a closed position. A resilient member biases the vane toward the closed position. When the vane is in the closed position, the vane covers 80% to 97% of the cross-sectional area.

    摘要: A dual exhaust system includes a first exhaust component defining a first exhaust path and a second exhaust component defining a second exhaust path that is different from the first exhaust path. A first valve is associated with the first exhaust path and a second valve is associated with the second exhaust path. The first valve and second valve operate independently of each other to vary exhaust flow and provide sufficient noise control for varying applications.
