    Black emulsion on the pipe of the rear silencer...

    Hello everyone, my cats are rattling. That's why I took the spout off and disassembled it. I discovered this black stuff on the rear silencer.

    Is that normal?

        Looks like water / carbon. Did you start / stop your car before it was fully warmed up? If so, there's normally a good amount of water in the exhaust from the cat.

            Looks like wet carbon to me. Pretty normal. Carbon and water are byproducts of exhaust after it runs through a catalyst. I wouldn't worry.

                    You wouldn’t happen to know the part number by any chance?
