The 'bong' needs to stay there. I don't like putting holes in stainless steel. If I remember, I will crawl under and take temp readings of before/after cat.

The rear O2 sensor, yes you do have one, is covered by a plate with 4 12mm(?) screws. The plate goes across the car and covers part of the exhaust. The sensor wire actually has a holder to that plate.

Remember, you also have an EGR, which may be clogged or has a bad vacuum line.
