An exhaust control device for an exhaust system for an internal combustion engine specifically applied to a motorcycle. An exhaust control device is incorporated that includes a single valve body having a plurality of exhaust gas passages that cooperate with each of a plurality of exhaust pipes that extend from the engine to the valve body. Parallel valve shafts are supported in the valve body and support valves that control the flow through the exhaust gas passages.
