Even a dual exhaust isn't going to solve the issue. The issue is ambient air hitting the O2 will cause the O2 sensor to false lean. With a dual exhaust you will still have sensors on each bank. If you are putting a split manifold on 4 cylinder and only putting an O2 on one pipe the ECU won't be able to monitor the burn cycle on the other cylinders.
