The one sensor is in charge of feedback for the entire fuel system, it needs to see the full amount of exhuast but not because of metering or trim, (which an O2 sensor actually does) but because of balance. If one side develops an injector leaking and the sensor is only in the other side it will not set a rich code and may cause some cat converter damage
Now...without a catalytic converter the point is moot.BUT performance may suffer and a lean condition (such as a plugged injector)could cause damage to the engine and no early warning would be sent VIA the engine light.
It would be Ideal to use an x pipe or an H pipe, and place the sensor just downstream of the crossover so that exhaust pulses from both sides of the engine cross over the sensor. If you have a single wire sensor it needs to be close to the engine in the exhaust stream. It needs to be hot to work properly, exhuast heat performs the task. If you have a 3 or 4 wire sensor placement is not uite as critical as the extra wires are for a heater built into the sensor so it works sooner and stays more stable through the entire operating range of the engine.
So in short it would probably be OK having the sensor in one bank only but it would be a better idea to have it in the downstream just after the crossover, for peace of mind if nothing else.

|plazawag54||What I should do then is create an X pipe or H pipe exhaust and install it in the intersection. Maybe???|

|66SSImp454||It is best to have the oxygen sensor read the entire engine. When you move it to just one side you get fuel control for only that bank.|

|plazawag54||I only have one in the system. Do I need to add another one? The question was if I could run the sensor in one side of a dual exhaust and not have any computer problems.|

The 2nd sensor is not used by the computer to adjust AFR, so it should not cause a problem. Just make sure its mounted properly (fitting on the top of the pipe so that water does not condense and pool on it ) and connected to the computer.

Ok Zen Masters,
The drivetrain in my car is a 95 5.2 magnum with matching trans, computer, injection, ect. All stock stuff. There is one O2 sensor downstream of the Y pipe and I want to dual it out. Can I install the sensor in one side and get the same results? Or will it mess with the computer? Im grateful for any advice.
