I have a CA spec car... this means, my car has 2 o2 sensors instead of one. when I go turbo (hopefully very soon) I'm sure the downpipe will only have a slot for one o2 sensor... so, is there like a resistor or something I can do so that my car doesn't freak out from only having one o2 sensor?

heres what you do.
most (99%) of widebands also output a narrowband signal, that will replicate your normal o2 sensor.
you place the wideband in the lower bung of the DP, (like dustin suggested) and wire the extra wire to your ecu, and that gives the ecu the 2nd O2 signal it needs, and you have your wideband.
dan, the cali spec has both sensors in the DP.

so, where did you get the berk technology downpipe with 2 o2 sensor bungs, or did you have one welded on?
