Abstract
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.
