  1. o2 sensor is behind cats,
    Has anybody hollow cats out ?
    will it toss out a code with cats hollow out and 02 sensor installed?
    nowt worry about insp.
     
  2. No, but if u hollow out the cats it could cause hp issues, not sure about the 5.0 but some motors need back pressure to work properly
     
  3. Had a 92 sc with no cats, I used the o2 adapter to pull the sensor out of the stream and back a bit further, never threw a code
