ABSTRACT:
An exhaust system comprises a muffler and a Helmholtz resonator. The muffler comprises an exhaust inlet aperture for receiving exhaust gas into the muffler, an exhaust outlet aperture for discharging exhaust gas from the muffler, and a resonator aperture. The Helmholtz resonator is at least partially external to the muffler and in acoustic communication with the resonator aperture. An associated method is disclosed.
