I'm confused. 2000 SE's have small pre-cat in the header. When you replace the header you lose the pre-cat. But how many O2 sensors does your car have? Ours (B14's anyways) have an O2 sensor in the header and one in the cat. A Hotshot header will have a premade tapped hole for this O2 sensor. Why do you want to relocate your O2 sensor to the rear of your normal cat?

we have one o2 sensor on the precat and one in front of the 2nd cat. Its about a foot in front of the 2nd cat. So i would have to extend the o2 sensor to reach behind the 2nd cat.

you can disconnect the negative terminal off the battery for a little while. i just do it for overnight. makes it easier for me.
