Abstract
An exhaust sound control system for vehicles includes an exhaust valve device that controls the volume of exhaust sound by controlling the amount of exhaust gas flowing through a muffler. In a sporty driving mode, exhaust sound is permitted to be transferred to the interior of the vehicle, and in a silent driving mode, the volume of exhaust sound transferred to the interior the vehicle is minimized. The volume of exhaust sound transferred to the interior of the vehicle is varied depending on the driving mode desired by the driver. Accordingly, the sensorial quality related to sound generated while driving is improved.
