    Abstract: The invention relates to a silencer (1) which is for an exhaust gas installation (2) of a combustion engine, particularly of a motor vehicle, and which comprises a silencer housing (3) that encloses a housing inner chamber (5), and at least one hollow body (4) in a half shell construction that is arranged in said housing inner chamber (5) and that conducts exhaust gas, the two half shells (14, 15) of the hollow body (4) being fixed to each other in the region of a separating plane (16). The assembly of the silencer (1) and hollow body (4) can be simplified if the two half shells (14, 15) are fixed to one another using fixing elements (17, 18) that are designed directly on the half shells (14, 15).

    Abstract: An exhaust silencer assembly includes an exhaust duct (22A;22B) and an exhaust silencer (20A;20B). The exhaust silencer is disposed about the exhaust duct and has a plurality of solid baffles (24a-24f;34a-34e;46) and at least one perforated baffle (26;38). The exhaust silencer assembly is disposed downstream of an auxiliary power unit (16A;16B) and at least partially attenuates the downstream noise of the combustion gases that result from operation of the auxiliary power unit. In one embodiment, at least one of the plurality of solid baffles is disposed to extend axially between generally radially extending solid baffles, perforated baffle(s), or partially perforated baffles. The axially extending solid baffle allows for cavity depth variation in the silencer to optimize tuning of particular frequencies from the auxiliary power unit.
