Abstract

A process for manufacturing a muffler for an exhaust system of an internal combustion engine, provides a manufactured muffler with a muffler housing with a housing jacket (14) that is elongated in a direction of a housing longitudinal axis and with at least one housing bottom (26) carried on the housing jacket (14). The process includes the steps of providing the housing jacket (14) with a stop formation (50) in association with at least one housing bottom (26) to be carried on the housing jacket (14), providing the at least one housing bottom (26) to be carried on the housing jacket (14), and positioning the at least one housing bottom (26) on the housing jacket (14) such that the housing bottom (26) is in contact with the stop formation (50) associated with the housing bottom (26).
