o2 sensor placement

I am installing a 3 wire o2 sensor for a air fuel gauge. my question is would it be better to put the sensor after the Y or in one of the headers?

Re: o2 sensor placement

now in the pass side would that give a better reading than in the y-pipe. would the y-pipe give wierd readings to the air/fuel gauge?

Re: o2 sensor placement

I said that because the ECM O2 sensor is in the driver's side and having two on that side would be cluttered. It really doesnt matter but having it in the y-pipe means a long length of wire. I put mine in the passenger side so I can monitor the driver's side on my laptop and the passenger side thru my gauge.
