Catalytic converter
The engine S63 TOP has a double-walled catalytic converter for each bank. The catalytic converts no longer have decoupling elements.
The known Bosch oxygen sensors are used. The control sensor is located in front of the catalytic converter, as close as possible to the turbine output. Your position was selected so that all cylinders can be recorded separately. The monitoring sensor is positioned between the first and second ceramic monoliths.
The graphic below shows the catalytic converter pipe with the integrated components.
