Performance Curve Thunderbolt Spin Cat
I just changed out the exhaust on my new XJ. New downtube back.
I bought a Thunderbolt Spin Cat with o2 port because it was recommended here and said it meets the requirements.
I'm now getting a CEL. I will double check this tomorrow, but I believe it's for the 2nd o2 sensor.
After some intensive searching I've found that this cat can be a problem for some Jeeps. What can I do about this? If it meets OBDii requirements why is it throwing a code? Is there anything I can do to get it to stop throwing the code other than replacing the cat again?
Please help, I need to get this up and running so it will pass inspection here in NY.

Hmm I am curious to know the answer as well. I have the same cat I am about to install on my 2000 XJ and I definitely don't want to install it if it's going to throw a CEL.
Also, where did you get your downtube? Is it custom or what? Seems like no one makes aftermarket downtubes for these XJs.

I'm new to exhaust work so I genuinely don't know.

I can't track down the down tube on Advance or Autozone, at least for my 96. Maybe they have something for different years.

So did you put it into a piece of straight pipe after the cat then? I don't understand why that would work vs the location that it's at now. Does that little bit of distance matter that much? Isn't it still the same exhaust content? I'm new to exhaust work so I genuinely don't know.

So the code says downstream o2 is not working at all. Going to clean the connectors and apply some dialectic grease see if that clears it up. Hoping it's just a bad connection and not a faulty sensor.
