A structure for reducing exhaust noise in exhaust system for vehicle is provided to maximize the noise reduction efficiency by allowing exhaust noise exhausted from each exhaust port to be offset to each other by interference of sound wave. A structure for reducing exhaust noise in exhaust system for vehicle comprises a connection pipe(10) connected to each exhaust pipe(100) such that sound wave of exhaust noise generated in a dual muffler system has a phase difference. A chamber section(20) for adjusting a phase difference is integrally mounted at the connection pipe(10). The connection pipe(10) is installed before or after a main muffler(160). The exhaust pipe(100) shares rear pipes(120) through the connection pipe(10). |
