Abstract: An engine sound enhancement system includes a conduit in communication with at least one of an intake manifold and an exhaust manifold of an engine. An interface is arranged at least one of within the conduit and between an inlet of the conduit and the at least one of the intake manifold and the exhaust manifold. The interface is responsive to pulses within the at least one of the intake manifold and the exhaust manifold, wherein the interface is configured to transfer the pulses into the conduit.

Abstract: A wastegate system of a vehicle includes: a wastegate valve configured to regulate exhaust flow through a turbine of a turbocharger of an engine; a wastegate actuator including a lever that is mechanically coupled to the wastegate valve via one or more linkages and that is configured to move linearly based on a pressure within an interior of the wastegate actuator; a resonator that is fluidly coupled to the interior of the wastegate actuator via a first one or more hoses and that is configured to counteract force attributable to pressure changes in the exhaust from combustion events within the engine; and a regulator valve that is fluidly connected between a pneumatic source and the resonator via a second one or more hoses and that is configured to regulate the pressure within the interior of the wastegate actuator.
