Abstract: An exhaust system for an internal combustion automotive engine, such as a V engine or boxer engine, includes a left exhaust tract connectable to a left group of cylinders and a right exhaust tract connectable to a right group of cylinders. Each exhaust tract includes a tract structure defining a tract inlet for receiving exhaust gas ejected from the group of cylinders to which the exhaust tract is connectable, at least one exhaust outlet opening into the atmosphere, and a connection pipe extending between the tract inlet and the exhaust outlet. The connection pipe includes an inlet aperture for receiving exhaust gas from the tract inlet and an outlet aperture for transferring exhaust gas towards the exhaust opening. The left and the right connection pipes are joined to realize a pipe junction such that the connection pipes form a common connection aperture for transferring exhaust gas and the exhaust system includes at least one valve member for opening or closing the common connection aperture.
