yes the o2s can stay but well i would recommend doing what i did with the electrical box? You need resistors to get the super clean look but you can sim it and leave the o2s in your exhaust you just might need a lot of wire? You need a voltmeter (i know there is a better name for this) that will be able to tell you what wire is what. I'd reroute my o2s into the drug bin get them mounted to something then sim it. Since I'm having so much trouble with my awd system I'm doing the swap to an I. Bought a 325 part car I'm taking the D/T if anyone needs parts let me know. my mistake it's a 99 328I if anyone needs parts let me know i might have em!!!
