ABSTRACT:
A muffler (12) has first and second outer shell members (14 and 16), and first and second inner baffle members (18 and 20). The inner baffle members are identical to each other and parallel to each other and rotated 180.degree. relative to each other about an axis (22) perpendicular to such parallel extension. The baffle members have oppositely facing laterally offset formed expansion chambers (32 and 34) partially overlapped to provide exhaust flow communication therebetween. The structural combination enables usage of identical components (18 and 20), which improves manufacturing efficiency and provides a cost reduction.
