I pulled the plugs and they did appear to have been running lean for quite some time. Jeff also recommended I still get the Uprev tune to address the lean condition due to the headers. (State of TN only uses OBDII for newer vehicles). After 2 days of driving, we cleared readiness and headed straight to the emissions booth and received a pass. I installed them, cleared the codes, removed the spoof box and soldered and shrink wrapped all the cut connections. I contacted Jeff at Cajun B pipes and he had me a set within a week. I had read about replacing the OEM B pipes with catted B pipes that have an O2 bung downstream from the cat unlike OEM and that seemed like it might help address the problem long term. I crawled under the truck and found the original installer had used crimp terminals which had pulled loose and must have shorted out. I learned on this and a Titan site about the Uprev tune but thought to myself that I had gone this long without it, so why now? Well, two months before this year's inspections I started getting P0420 codes again which should not happen with the spoof box in place. Over the course of the next 3 years, I was somehow able to pass OBDII in between bouts of P1268 and other codes referencing lean conditions. What I was unaware of though was that they ordered long tube catless headers that use a spoof box to get it to not throw P0420/P0430 cat efficiency codes. I thought to myself this is a no brainer. The mechanic said he had done one set prior for a QX56 and parts would be about $800. I wondered if an aftermarket part might be more reasonable so headers came to mind. My independent mechanic typically only uses OEM parts and if I recall correctly, a pair of catted manifolds was right at $2000 before labor and this was in 2012.

At around 115k, my wife's Armada started making the tell tale sounds of cracked exhaust manifolds which I understand is VERY common with these vehicles.
