exaust 02 sensor question/ pipe poll

first off my question is simple.

If you run a pipe from each header all the way back, use 2 cats, then your left with two pipes and one o2 sensor. Would this not cause a problem with your ecu trying to compensate for only sensing one pipe? Are there any maximas out there with true duals?

I thank you for any input you may give on the subject.
