The exhaust muffler comprises a body (12) of ceramic material which is enclosed within a metal case (1) defining an inlet chamber (16) and an outlet chamber (18) for the exhaust gases. A blanket (20, 22) of refractory fibres resisting high temperatures, assembled with a very small amount of binder and substantially without water of constitution, is highly compressed between the body (12) and the case. A sealing element (24) surrounding the body (12) is interposed between the blanket and the gas outlet chamber (18).

A catalytic exhaust muffler comprising at least one body of ceramic material, of the honeycomb type, a metal case coaxially enclosing the body and defining with the body an annular space around the body and inlet and outlet chambers at axially opposite ends of the body a blanket of fibres interposed between the body and the case in said annular space, the fibres of the blanket being very resistant to high temperatures, said blanket being substantially devoid of binder and devoid of water of constitution and being highly compressed between the body and the case, said case comprising two half shells which have an arcuate cross-sectional shape and means interconnecting said half-shells, each half-shell having axially opposite end portions extending toward the axis of the body inwardly beyond an outer periphery of the body, and a sealing element surrounding an end of the body of ceramic material which is the closest to the outlet chamber and is compressed between said case and said body.
