Ok, I have searched and this search engine sucks...

Where should I have my o2 on my exhaust? I have a tbe with testpipe, and I currently have my rear o2 in the testpipe. I have a bung in the catback I could use, would that be suitable placement for the wideband o2? Thanks guys

 

This should help you as far as location of the wideband O2 sensor.

 

search function is great.....there are TONS of threads about this.
First place to check would be HOW-TO section .

 

THe search function is great btw.

On the downpipe, 2 inches before the flange in the 3 oclock position
