I noticed on pics of all turbo kits the primary o2 sensor that normally goes on your headers does not go on there with a turbo kit. Where does it go? I know for the S pipe you put your secondary and then the one for your AEM UEGO guage. That leaves the primary o2 sensor un accounted for? where the hell do you put it?

probably goes on the downpipe.

it goes into the downpipe after the turbo before the s-pipe.

Our kits have the primary o2 sensor mounted on the downpipe.

Our downpipe is 2 pieces the piece that connects to the turbo and the s-pipe. We put 3 bungs all together in the entire piece. 1 for stock primary sensor in the upper half, and 2 in the s-pipe (1 for stock secondary and 1 for a wideband O2)
