Hello guys new to the forum, this is actually my fathers' car (2014 GS350) I personally own an F30 328i currently but I am installing an invidia mid pipe and axle back set up on his car for him! I have the axle back on no issues the only thing I have been struggling with is the removal of the driver side rear O2. TLDR; the only snag is the driver side O2 not loosening from the pipe. I've given up hope of actually getting it out of the pipe (the head is getting stripped due to all of the struggle of trying to remove it) and have purchased a Bosch replacement to put into the new pipe. My main issue now is locating the O2 connector and there seems to be absolutely no information for this gen specifically on finding it. From what I gathered it is under the drivers' seats carpet, I see the grommet hole from the bottom of the car leading up to it but I have no visual on where it could possibly be up top. I have found some general info on removing trims and everything to get to the general area but since it isn't my car I am trying to be as careful as possible removing his interior bits. I was hoping that someone else has some guidance or visuals possibly to help me figure out the easiest way to disconnect this O2 so we can remove the pipe install the new mid pipe pieces and install the new Bosch O2. I appreciate any help I can get!
