ABSTRACT:
A muffler designed at least about the exterior surface by a barrel with end plates. An inlet tube and an exhaust pipe are associated with the end plates, respectively. The external joints are formed by locked seamed roll joints and S-shaped deformed joints to avoid welding at the exterior of the muffler. Tubes extending between baffle plates may also employ the S-shaped deformed joints. Joint tubes having some ability to telescope axially with the other internal components provide thermal stress relief.
