I see a pipe welded to a jackstand with an o2 sensor portruding out the side which is inserted into the tailpipe of vehicle.
Anyone else seen or used o2 sensor in pipe sticking out rear exhaust location?
I always thought it necessary to remove (1) front o2 sensor
OR
Install seperate dedicated o2 bung before catyltic converter for dyno testing
