Abstract
Stamped formed mufflers and a process for forming stamped formed mufflers is provided. The mufflers are stamp formed from master dies having a plurality of die subsets removably mounted therein. At least one subset may include several die inserts removably mounted therein. The subset and insert dies are selected to effect the acoustical performance of the resulting muffler. Thus, a system of mufflers may be formed having generally the same pattern of tubes therein. However, selected mufflers in the system will have portions thereof which are different from other mufflers in the system, depending upon the particular die subsets selected for mounting in the master die, and the particular die inserts selected for mounting in the subsets.
