    The Cobb dp is meant to be used with stock catback?

    I just dont want to go from say a ~3" dp to a ~2.5" catback and it leak or mess up flow due to the size difference.

    Then just buy a full TBE, one that is 3" all the way back.

    Also 3" all the way back is better imo less back pressure.

    I do not wish to have a full catback due to sound, which is why I am looking for a dp that connects and works well with the stock catback.

    Grimmspeed downpipe adapter.
    The stock catback is not restrictive.
    Done and done.

    From their website:
    The end flange uses the stock donut gasket and factory spring bolts to aid in flex, longevity and proper fitment. This provides an improved seal compared to other methods, as well as reduced noise. An additional benefit is that it makes the COBB 3" Downpipe compatible with any cat-back exhaust that mates to the factory cat section.

    But there is this as well.

    As I searched for this thread again, I came across this post and realized I never updated it. Here's the link I referred to:
