In a thermal afterburner and muffler for internal combustion engine exhaust gases, an elongated counterflow first combustion chamber has a central inlet for receiving the exhaust gases. A second combustion chamber includes first and second combustion regions, with the first combustion region receiving exhaust gases ejected from the first combustion chamber. The second combustion region includes a transversely extending baffle and an ignition element centrally located therein. A third combustion chamber includes first and second combustion compartments with the first combustion compartment surrounding the second combustion chamber and connected to the second combustion region through a partial flow-forming element and has a heat reflective inside surface area. The second combustion compartment surrounds the elongated combustion chamber and receives combustants from the first combustion compartment. A ceramic fibrous material at least partially surrounds the second combustion compartment. An elongated axially extending duct interconnects an exhaust outlet of the afterburner and the outlet of the second combustion compartment.
