Hi Guys,
I have a rubicon 2009 3.8 with a few modifications.
The problem is after instal borla headers inox appear in my dash "check engine"
Obviously is for O2 sensor.

Someone fix this?

Did you wire the O2s properly?

I had the complete Borla setup on my 09X that i recently traded for a 12Sahara Unlimited. I had the same issue, fortunately i have a Diablo Sport Trinity T-1000 tuner. The CEL comes back with o2 banks 1 and 2 running too hot, for obvious reasons. Are you running their long tube headers? I never found a fix however it never gave me any issues. My tuner could clear the code but it would return in a few days so i just let it linger. I ran that setup for nearly 5 years with no issues, and loved the way it sounds. I still have the entire setup, going to dabble with the headers this week to see if they will bolt up to the 3.6, if so then im custom fabinig from the headers back to he dual muffler to bolt this puppy up to my "new" rig.

If you are running the long tubes, you no longer have cats which is what is throwing the code. Even with a Diablo the codes do occasionally come back.
