3. I used the old front O2 sensors in the rear after the cats. I extended the cable using Teflon insulated wires, silicone tape from Home depot and a Silicone jacket I found at Napa. You must crimp the wires according to Bosch engineer. Do not solder.
I had the car on a Dynojet and got 239 Rear Wheel HP. and it feel great!
Hope this helps. Let me know if you have other questions.

Rich, I thank you very much for this quick and concise response. I understood what you did perfectly. Let me get this though, front O2 and rear O2 are not unique parts and they can be interchanged, right? As someone pointed out that yr.00 to 04 have 4 sensors and although some parts supplier indicates they are difference in front and rear, they can be the same sensor ( range to detect remaining oxygen is wider? ).
