A muffler with a catalyst, comprising:
- a muffler body having an open end;
- a muffler closure, detachably attached to the muffler body to close the open end, the muffler closure having an inner surface;
- a thermal insulation acoustic layer, mounted over the inner surface of the muffler closure, for thermally insulating the inside from the outside of the muffler closure, the thermal insulation acoustic layer having an inner surface;
- a catalytic layer, superposed on the inner surface of the thermal insulation acoustic layer, for achieving a catalytic reaction with exhaust gas to clean the exhaust gas, the catalytic layer having an inner surface;
- and
- a porous holding means for holding both the thermal insulation acoustic layer and the catalytic layer against the muffler closure, the porous holding means having an inner surface contacting the exhaust gas.
