An internal combustion engine system includes a combustion engine configured to produce exhaust gases as a product of a combustion reaction. An exhaust discharge pipe coupled to the internal combustion engine, and an adaptive valve assembly. The adaptive valve assembly is coupled to the exhaust discharge pipe and configured to receive the exhaust gases prior to the exhaust gases reaching the atmosphere. The adaptive valve assembly includes a valve flapper arranged in the passageway and configured to pivot about a flapper pivot axis from a normally-closed position to an opened position.

A vehicle exhaust system includes a first exhaust gas path and a second exhaust gas path. At least one valve is positioned within the first exhaust gas path and an active noise control system is associated with the second exhaust gas path. An example method includes, providing the first exhaust gas path with a first tailpipe having a first outlet and the second exhaust gas path with a second tailpipe having a second outlet separate from the first outlet. The valve and the active noise control system are controlled simultaneously to control noise generated by the vehicle exhaust system.
