Default Minimum length for exhaust?

Anyone know what the minimum length is for the exhaust on an LT1 in order to keep the oxygen sensors working correctly?

I have a pretty complicated Y-pipe with cutout in mind I'm going to make eventually but for now I just want to bolt on some header extensions with turn downs...how short can I get away with running?
