Doesn't matter what changes are made AFTER the post-cat oxygen sensors. The car is "numb" to these changes and will not throw a CEL for anything downstream of the post-cat o2's. So as long as the primaries and both sensors are installed (before and after the primaries), any setup should not trigger a fault.

It doesn't make sense to me that this would trigger a fault if the stock primaries and sensors are left in place.
