    I have a 2006 Om642 3.o v6 turbo diesel and wondering how you determine a catalyct converter and a dpf? Reason being I see a small cubed section twice the size of the exhaust pipe coming just after the turbo and then there's another big box section near the gearbox after the downpipe that has a temperature sensor and a oxygen sensor just after it? Reason being is I want to remove the big box section if possible without bringing codes up?

    A DPF will have 2 pipes for measuring the pressure differential, they lead to the differential pressure switch.
    And there is a temperature sensor that will have a flex to its connector.
    If you don't have these on what looks like a silencer you don't have a DPF.

    I had a 2004 C class with a DPF, it was an option apparently.
