Do you have bungs on your pipes for the rear O2?s You'll get a SES if those are missing regardless of how the fronts are functioning.
The real solution is to tune those DTC's out. Do you know somebody who can tune? You're going to want some tuning to maximize your LT's performance anyhow.
BTW, I have a extra pair of extensions lying around. I'll ship 'em to you for $20 if you want to try 'em. Not a big investment and they just may work. PM me if interested.

Steve will get you sorted out, then. The typical codes thrown by the front O2's on LT's (slow response, etc.) don't have much effect, if any, on AFR's. Nevertheless, I agree that it's best to have them in top working order for your tune. After that, you can tune out the typical DTC's and not worry about them anymore. That's what did.

Get the densos they are about the same price as bosches and are OEM for every new gm vehicle. If your o2's have 90k on them they are probably already worn out and not switching very fast usually people who have lts and use their old high mileage sensors will crap them out in not to long of time. The bosches work for some people but I have seen the 2 switch side by side and can tell you the densos and ngks do it much faster also for every person who has the bosches it seems there are just as many people who have issues with them. Heres my story I got headers at 102k and used extensions one o2 crapped out in a month, ok i went to the store and got a bosch replacement because i needed the car. That bosch lasted 3 months and took a dump I finally said screw it and ordered the densos they've been great too me for almost a year... Again no issues with extensions however with your sensors being that old they probably could use a new set and so why not just eliminate the need for extensions?

I was just about to order new stock 02 sensors and some extenders. I think I will go with some corvette rear 02's after reading this. Thanks for the heads up. These would be for rear 02 out of a 02-04 c5 correct?
