O2 sensor placement

Getting ready to put my FSW header in, and want to know exactly where to put the sensor for the wideband. I know the down stream gets deleted and the up stream goes into the bung on the header. I've seen people put them in one of the primaries, but that makes no sense to me because I think you'd want to measure combined exhaust gasses, not just a single cylinder.

I'm thinking to weld the bung into the flex pipe. Any suggestions?

Thanks
Joe

I'd be welding a bung as close to the collector as possible. The flex pipe is fine as long as you use a solid portion of the pipe.

I know it needs to be in the solid section of the flex pipe assembly. I was thinking an inch or so from the flange end that bolts to the header.
