In the I-pipe by the trailing edge of the passenger's
door, where I can get at it without jacking the car
up and the cable can come inside short & snug. I
use mine only occasionally fur tuning, not full time.
My cat shells are empty, so no worries about the
gas mixture being modified. WBO2s want to not be
-too- close to the exhaust ports because they need
the heater, not EGT, to be in control of operating temp.

No cats, I put it 4 feet back of the headers so the sensor won't get burnt up.
I would put it as far back as you can, they warn you about that sensor getting too hot.

FWIW ... I really don't think that it matters if it's pre or post cat in most cases...... for years ... you go in for a dyno tune.. they stick that probe up your cars *** for wideband... guess what .... it's not going past the cat heh...
There was also a post on an aussie ls1 board where someone tried pre and post cat and the differences were negligable ....
If I had cats on my car I'd try it.... If I had an I-Pipe I'd try thta way too heh
