1. An exhaust sound enhancement (ESE) system for a vehicle without an internal combustion engine, comprising:
a plurality of speakers including a woofer and a midrange speaker;
an amplifier configured to generate and play sounds on the plurality of speakers; and
a tuned exhaust assembly with a housing configured to resonate, amplify and inter-modulate the sounds from the plurality of speakers to mimic exhaust sounds that would be produced by a predetermined internal combustion engine, the tuned exhaust assembly including:
a mixing chamber configured to inter-modulate low frequency sound waves from the woofer and midrange frequency sound waves from the midrange speaker to produce the mimicked exhaust sounds; and
one or more exit ports configured to imitate an internal combustion engine vehicle exhaust port, the one or more exit ports configured to receive the inter-modulated low and midrange frequency sound waves from the mixing chamber and direct the mimicked exhaust sounds out of the one or more exits ports to an exterior of the vehicle to produce an authentic internal combustion engine exhaust sound on the exterior of the vehicle.
