a/f gauge

So my little brother just bought me a air/fuel gauge as a gift.
After reading the instructions, I know how to hook it up, but if didn't say where would be the best place to put the 02 sensor in the exhaust. I'm running the racing beat road race exhaust, where it collects at the rear end. But I thought that may be too far back for a sensor.
Thanks for the help

Same exhaust here. I put the sensor on one pipe only. Worked pretty well. It is in the "center section" a few inches after the dual pipe flange. Angled up 10 degrees as mentioned in the instructions.

The short collected header for a gslse has the bung welded on it.
The UNcollected road race header for the gsl se "what I have" does not come with a bung welded to it.
That just came from racing beat I just talked with them and they don't put bungs on the road race headers.
However Mazda trix sells a racing beat road race header that THEY add a bung, but they also add a tube for the aux.ports on the header which would not work for me since I'm using a Holley.
