O2 extender installation

to be install before Cat or after Cat ?

kindly advise ?

O2 extenders are installed on the before cat O2 sensors.
O2 extender would be better than nothing but in all honesty,
I would recommend using a digital EFIE instead of O2 extenders.
This will give you more control over your system.
