I have a 2001 Integra and the primary o2 sensor is on the header. I got a new header because the old one is cracked badly and i have to cut the cat at the flange ( cat was rattling like crazy anyway ). I will get a cat to pass inspection in the future.

So my question is if i move the primary o2 sensor a little further back. Like on the test pipe and have another o2 sensor bung for the secondary. Will i get a CEL or will i be fine?
