building an on road y-pipe /cats/LTs want a direct bolt on 02 sims vs: software edit (removing rear o2 sensors) vs rear o2 bungs and having rear o2 sensors.
1. heard using o2 simulaters is not a good idea because they fake out the PCM so if theres an air to fuel related problem like air mass sensor or throttle position sensor or other related sensors the sims or coving these problems up
meaning there mite be a problem that I would like to know about.
plus they wear out real quickly.
2.removing the rear o2 sensors with a software edit I'm thinking it's similar to the above but really have no idea.
3. prefferred choice would be to use rear o2 bungs and try to place the bungs in as close to the same mearsurment from rear of the cat brick.
any advice on this is apreciated

Either way is fine. Your best bet is to get the code deleted, but if you dont have ls1edit or hptuners then just get some sims. I have had sims on my car for 1/2 a year now and not had any problems with them.

Rear O2's only monitor cat performance as far as I know. Using sims is fine...or you can get some software and delete the codes out. Until you spend some time to learn more about the PCM and how it works, I'd suggest getting the sims. The software would be overkill if that's all you wanted to do. Now, if you wanted to tune your car and are willing to invest the time/money in the software (and a wideband O2), then go for it.
