E 350 CDI
The exhaust system for the V6 diesel engine 642
consists of an oxidation catalytic converter, a diesel
particulate filter and one rear muffler for each pipe. All
the emission control components are near-engine
mounted. The exhaust pipe is air gap-insulated as far
as the diesel particulate filter.
The connecting points in the exhaust system are
located downstream of the oxidation catalytic
converter, downstream of the diesel particulate filter
and at the rear exhaust system.
The two tail pipes are integrated into the bumper
cover on each side and each one ends in a tail pipe
finisher.

E 350 CGI and E 500
The exhaust system for the V6 and V8 gasoline
engines consists of one firewall catalytic converter
each for the right and left cylinder banks.
Downstream of the two firewall catalytic converters
the exhaust gas flows through the front muffler and
the underfloor catalytic converter via the center
muffler to the two rear mufflers, before leaving the
exhaust system through the tail pipes.
The connecting points in the exhaust system are
located downstream of the air gap-insulated manifold,
downstream of the front muffler and after the under-
floor catalytic converter.
The E 350 CGI is fitted with a trim finisher on the tail
pipe, while on the E 500 the finisher is integrated in
the bumper cover and the tail pipe ends in the finisher
without touching it.
i Note
New devices are available for exhaust extraction
on vehicles with tail pipe finishers integrated in the
bumper. These are described in more detail in the
"Workshop equipment" chapter.
