I want to run off my 3" downpipe and test pipe directly for right now. My question is what do I need to do with the second o2 sensor on 2g's? Do I need to remove it completely?? I know it is just there to ensure the cat is working right. For all of you with a cat back and running no cat what was your solution for this? Is there anyway to get around it without removing the 2nd o2 sensor?
 
Just ziptie it up out of the way. If you unplug it you will have a CEL no matter what you do. A lot of people have good luck with tieing it out of the way and don't get CEL's.
