HO2S removal
I have a 92 bronco with a 351w, I have removed the cats and muffler, but it is still a fake dual, i want to know how to make it into a true dual, the muffler shop i talked to said that the oxygen sensor needs the heat from both exhaust manifolds to operate properly.
My question is What exactly will happen if i remove the HO2S altogether? I know the check engine light will come on, and the fuel/air mix will go to the preset default, but performance and MPG-wise will there be any noticable effect and how do i correct this?
I plan on getting headers soon, i don't know if this makes a differance

the first pic is of my HO2S from the passenger side front wheel well
the second is of where my cats were, whats the old rusted plugged pipe? the muffler shop plugged it when they removed my cats
the last pic is for reference, it is a wider angle of the second pic

Your truck will run off the tables and more than likely will run rich and eat more fuel.
Just get a bung and drill a hole and weld it in to at least let it read some exhaust
from one side, It would have some idea what the motor is doing. It will get hot enough
if you keep it about the same distance as it is now and you will be fine, If it has 4 wires running to it is a heated O2 sensor and will heat itself.

Why do you want to run a true dual? You really aren't going to gain much other than sound, and I would think a X-pipe would be the most effective option. That way you can run the duals all the way back and still get the best O2 placement, optimum scavenging at low rpms, and optimum bottom end torque. I don't consider an X-pipe to be true dual, but its pretty close to it. and it does let you have all the best features of a single exhaust and all the best features of duals. It looks like a dual, it sounds like a dual, it has the top end performance of the duals, and the bottom end grunt that some dual systems lack. (Note, I said "some" this time for anyone reading this. If the duals are done wrong they could be a downgrade. If they are too large, you will penalize the bottom of the powerband.)
