Abstract
The disclosed inventive concept provides a further achievement in efforts to produce a tunable exhaust sound for a vehicle. The system provides a tunable exhaust system including a tunable resonator and a pair of tunable mufflers. The tunable resonator includes a housing including first, second and third expansion chambers. A pair of bank-by-bank exhaust conduits extends through the housing. At least one of the conduits includes a band of peripheral perforations within the first expansion chamber. The band is formed at an angle relative to the long axis of the conduit on which it is formed. The mufflers include inlet and outlet pipes. At least one of the outlet pipes includes a variable exhaust gas flow assembly. The variable exhaust gas flow assembly includes a vane shaft, an exhaust gas regulating vane attached to the vane shaft, and a vane actuator for regulating the position of the vane shaft.
