A little confused on why you would need a 2nd o2 sensor bung for an S14 application. Because the real cat on the S14 is built into the downpipe then it bolts to the fake cat then that bolts to your cat-back exhaust. So if you put a 2nd o2 bung on the downpipe when you eliminated the real cat, it would be useless right? and wouldn't the check engine be on all the time? and wouldn't you be running rich due to the lack of o2 sensor? but then even if you did ad the 2nd o2 sensor, what good would it do? the whole point of the 2nd o2 sensor was to see if your cat was working...

I guess I just need schooled on this subject, cause i"m missing it.

-Thanks

Its an optional addition to the downpipe that some people get to run their wideband O2 gauge.

Wait, so how would you prevent the check engine from coming on for the o2 sensors? or is there no way to prevent it when going sr20det?

when you have the SR motor you also have the SR computer, there is no C.E.L. related to O2 sensor and the downpipe.
