Abstract
An audio system of a vehicle includes a detection module configured to detect an occurrence of a sound when a pressure measured by an exhaust pressure sensor in an exhaust system is greater than a predetermined pressure. A sound control module is configured to, in response to the detection of the sound, increase a magnitude of a predetermined sound to be output within a passenger cabin of the vehicle. An audio driver module is configured to apply power to a speaker of the passenger cabin of the vehicle based on the predetermined sound.
