another exhaust 2017 CB question

[itstuantran_imp]

If you buy the one for 2017 like Ruyjin Japan, it has 2 a/v bung holes. You will need either Bazzaz, PCV or other tuning devices which may have O2 sensor eliminators and that you don't need the O2 holes anymore . I have bazzaz installed wilt 2 O2 eliminators and the O2 sensors no more in use, just zip tied them.

if you install single side exhaust on 2017 CB with two(2) O2 sensors.
what should be done with left side O2 sensor?just disconnect?that can't be right?
