recently installed flow tech full length headers, don't know what to do with rear sensor wires, they are currently disconnected. do I need to tune it or just leave everything alone???

just tuck up the wires and your good to go. You dont have to get a tune for the rear O2's, it'll just throw a code and set off your SES light. A tune would get rid of that, and would also get ya some extra ponies.

buy some o2 simulators or get the pcm tuned. it is not good to have the check engine light on and driving with it all the time., because if some other codes decides to go up the check engine light will already be on and the guy would think everything is ok.

+1^^^ Just get some simulators. Its the easiest, and cheapest way to do it. Having your SES light on all the time is not a good thing, I know from experience

Where can you get the simulators at?

imo simulators are expensive. ws6store has them for $100. id put the money toward a tune, since you'll get a good amount of power out of that with headers.

Even if you dont go with a full tune, most tuners can turn that code off for you in a matter of minutes and do it cheaper than the $100 sims.

Yes but putting on LTs has changed our Air Fuel ratio also and you won't see a decent gain until you get a tune. Get a tune, you won't be disappointed. Your car will be better overall with one.
