New exhaust 02 Sensor placement opinion, would it be a benefit to put the sensor down on the Y-pipe or should I put it back in the original stock position?

Need an opinion, I'm replacing Exhaust components, Manifolds, Y-Pipe, and Convertor. The Y-Pipe I purchased has a place for an O2 Sensor. The stock o2 sensor is on the driver side manifold.

I would install the oxygen sensor in the original placement. Check out the diagrams below to show you the location. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.
