Abstract: A muffler for receiving exhaust gas from a combustion engine is disclosed. The muffler includes a casing and a pipe. The casing includes a shell coupled to first and second end caps that cooperate to define an internal volume. The pipe is disposed within the internal volume and extends substantially a length of the shell. Each of the first and second end caps includes a circumferentially extending flange engaging an outer surface of the pipe to provide support for the pipe. Each circumferentially extending flange extends at an acute angle relative to a shell axis of the shell. Each circumferentially extending flange is coaxial along a pipe axis of the pipe.
