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?
