all 4 o2 sensors are near the 2 mini cats so I would be suprised if there is another cat (but I do not know for sure).

man - 4 02 sensors just sounds expensive. I believe there are 2 cats. the 2 mini ones and that's it. will have to peek uunder the car later to check.

I am assuming the only one you can replace with a "High" flow would be the 3rd one. Thanks for the help.

before you order anything confirm how many you have by looking at your xj. It's possible rock auto is showing the 2 possible configurations, 2 mini cats or 1 conventional cat together.

If you have the 2 pre-cats, then the third thing you are thinking is a cat (the one out back before the muffler) is just a resonator. It's not a true cat converter.
