FG XR6T - where is the o2 sensor?

As per title, where is the o2 sensor located on an FG XR6T? 

 

Thanks in advance!!

there's one in the dump pipe from the turbo and there's another one after the catalytic converter. The one that matters is the one that's in the dump pipe.

that's correct as keith said. although I would suggest if you decide to replace one, you should replace other as well. reason being is whatever caused first o2 sensor to deteriorate is probably causing second one to deteriorate as well

I don't agree. Why waste money. I had the upstream O2 die at 50,000km. 5 years and 40,000km later the down stream O2 is still fine.

I agree. Upstream sensor is the one helping adjust fuel trims etc and is most important to be functioning at full capacity. Downstream is basically to make sure the cat is working, so leave it till it chucks a check engine light. Upstream one would be subject to to ton of extra heat so would have thought downstream will last longer too.
