An exhaust muffler is provided with first and second internal plates formed to define an array of tubes and a reversing chamber. A pair of external shells are engaged to the internal plates and define one or more chambers surrounding the tubes defined by the internal plates. A pipe extends across the reversing chamber defined by the internal plates and to the outlet. A portion of the pipe may be perforated to enable expansion of exhaust gas into a high frequency tuning chamber.
