An exhaust system for an engine is disclosed herein. The exhaust system includes a catalytic converter, a heat collector downstream from the catalytic converter, and a heat transfer system receiving waste exhaust heat via a thermosyphon evaporator for storage and/or use in a cabin heating system. In this way, waste heat is utilized to provide better cabin heating, particularly at engine cold start.
