o2 sensors, where should they be placed? I have a set of LTs and high flow cats, and the o2 sensors are located downstream of the cats. Are they supposed to be upstream? What kind of problem would that create?
I have a narrow band HP tuner, Ls6 engine with basic tune. Just trying to sort out some issues

I've never seen a set of (off the shelf) longtube headers that didn't have oxygen sensors in the collectors. If you have O2's downstream of the cats, look a little closer for the upstream O2's. I'm sure they're in there somewhere.
The downstream O2's are only there to verify the cats are working, they don't impact how your car runs. The upstream O2's are the one's that do work.
