Default oxygen sensor missing?

94 vert guys. Changed oil and filter yesterday and was inspecting the underside of the car for any issues.Happen to look at the oxygen sensors on the right side and had one before and after the cat. Looked at the left side and I only have a sensor before the cat and none after it ? Have a borla cat back exhaust system on the car and there is a place for a sensor after the cat, currently has a plug in it. Car runs great, is this normal?
Thanks

1994-95's only had one post-cat o2 sensor (right side). 1996 had o2's on both sides. That's the reason for the plug in the aftermarket cat-back.

Yep, normal. I actually unhooked and removed the one behind the passenger side cat and used an oil plug to cap it.
