    Seems to be pointing behind the muffler.

    I drew the arrow so disregard that. Look where the label line ends inside the muffler.

    I still think it is behind the muffler. The image seems to be see-through. I could be wrong, but that’s how it looks to me.

    I would hope youre right but Im almost certain about this one. Anyone that has a stock muffler sitting at home please check and take a look in the rear opening. Maybe a photo

    BTW yes there is a secondary cat inside on german cars at least. I didnt want to believe it but we sold a turbo kit to a customer in germany who said there was and when he cut it apart he found it to be true. So he had to add some more components to the exhaust to be Tuv approved.
