With a 5.4l you have at least 2 O2 sensors, one on each side after the exhaust manifold, before the y-pipe and cat. No rear sensors on my 99 either...

I'm not 100% sure but some states are stricter than others, so it may depend on where the vehicle was sold originally. example (California dealer)?
