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.
