The bung that I have on my headers is for the A/F sensor. I may get a bung welded into the pipe replacing the upstream cat for a wideband sensor, but thats later on.
I believe my cat is fine, and I may eventually replace it with a high flow cat, but I do believe that my only option for clearing the code for good is getting that URD attachment.
Thanks for all the help!

No problem. I'd be curious to know what actually fixes it. Instead of the URD sensor simulator you can order a new O2 sensor (Denso) and see if it clears. As most have said that's usually the culprit. Good luck.
