duel wideband o2 system

Im new to this forum so forgive me for asking for something that already maybe posted. I did look though and did not find anything. To my question: I have a 2001 suburban with an 8.1. I'm looking for a complete kit to install a wideband o2 sensor system in a duel exhaust setup. The truck already has 2 sensors from the factory. Im looking for something that will integrate easily with the latest HP tuner system. I have seen a gage that has two readouts for 2 sensors and would prefer that if possible. Cant seem to find where I saw it. Anyway, thanks for all the help.
