Header 02 sensor question Whats up guys. Finally got my headers installed and bolted in. Just have a question about the o2 sensors. So i pulled out the 4 sensors, 2 from the headers 2 out of the cats. I am not going to be running cats for awhile and i was wondering if it will run fine with just the two o2 sensors that bolt in to the headers? or do i need those other 2?

the ones in front of the cats with the flat connectors are needed. the ones behind the cats with the square connectors arent needed and can be tuned out. the ones with the square connectors are used to monitor the cats performance so if your gonna be running cats you can leave em in.
