If I remove the catalytic converter and cat-back and run open downpipe what do I do with the o2 sensor after the cat?

It just checks the efficency of the cat. You can run a resistor inline so you dont get a cel. Other then that it does nothing. It just tells you when your cat goes to shit.
I got my testpipe from ExtremeRS and he had the resistor with his kit. So I know he knows where to get one.

turbo8u> shut your SUCK
ZAO684: NIPPLE warning...maybe>?

resistor part number from radio shack is 271-1356. 99 cents for like a pack of 5 or so. put it in line with the black wire on the rear 02.

its different for different people. i have my rear 02 installed still and have 3 inch pipes from the turbo all the way back with two resonators. no CEL. i had a CEL when i had my straight pipe on non turbo though

so i dunno

I have a gutted cat, no resistor, and no CEL's.

If you do not have a CEL then your car must be slow.

im not sure you guys understood his question.i think he means a place to put the sensor as a temporary fix... i might tape it to the underbody or zip tie it to something under there. is this setup just for the track? if so, id tape it. if not, your gonna be reallllllly loud on the street.
