ABSTRACT:
A system of stamp formed mufflers is provided. Each muffler in the system includes a pair of plates formed to define an array of tubes therebetween. At least one external shell is securely affixed to at least one of the plates to surround the tube. The mufflers in the system have generally the same pattern of tubes therein. However selected mufflers in the system have portions which are different from other mufflers in the system depending upon the acoustical requirements of the particular muffler in the system.
