I bought the 6685 JBA LT's and they not only have welded 02 bungs on the collector but they also have one each on an individual header tube as well. I called to ask why and was told by JBA representatives that since the upper 02 sensors are narrow band, they can be placed in the single tubes to stop the problems that people have by placing the sensors in the collector. Of course I was told that you need to consult with your tuner about placement where you put your sensors at in the JBA headers.
I am not endorsing these headers BUT it seems that they've offered a solution to the problems that people have had before with sensors in the collectors.
