relocation of O2 sensor???
my room mate has a 2000 gt. he just got some headers off ebay, not sure what kind they are. now the guy that he bought them off of said that he needed to relocate the O2 sensor to the cat. i looked at the headers and it seems as if there is a spot on the headers for the O2 sensor? so anyone know why he said that? and it seemed as though he had the O2 sensor on the headers. i don't know too much about eclipses, so i don't have a sure answer for him. thnx

Re: relocation of O2 sensor???
you have to get a cat that has two threaded o2 sensor holes in it and extend the stock wires on your o2's and relocate them after the aftermarket cat. (if you have the 6 cyc w/ cali spec)

Re: relocation of O2 sensor???
the cali specs are more common than the fed specs. the cali has 4 o2 sensors. two directly off the where the manifolds connect to the head, and two after the smaller cats. your headers you got don't have converters connected so you can only install the two stock precat o2 sensors on the headers. the other two have to be located after the cat so you have to replace the cat with one with 2 holes after the converter and you have to extend the wires so that the o2 sensors will reach that far back.

Re: relocation of O2 sensor???
that's where i made the mistake and got the wrong cat at first. the o2's are pretty much hidden in shields and beside the converters (which can often be missed when examining). your best bet just to confirm it is to check for the wires/wiring harnesses. just to be on the safe side oh coarse
