ABSTRACT:
A muffler is provided comprising an array of tubes and a stamp formed external shell surrounding the tubes. The external shell is stamp formed to define at least one chamber surrounding at least portions of the tubes. The chamber extends away from peripheral portions of the external shell to define a three-dimensional volume. The chamber is characterized by a plurality of inwardly directed V-shaped grooves, with each groove extending continuously between opposed spaced apart locations on the periphery of each chamber. The grooves preferably define a parallel array of substantially identical grooves. The grooves strengthen the walls of the chamber and efficiently prevent shell noise.
