I have a new Bassani catted X-pipe for my 1996 GT that is waiting to be installed. I know that if I delete one or both pairs of O2 sensors I will get a CEL unless I use O2 sensor simulators (MIL eliminators) or "delete" them using my SCT X4 tuner. Can anyone please tell me any other pros and cons of deleting the upstream and/or downstream O2 sensors? (Right now I'm leaning towards keeping the upstream O2 sensors and just deleting the downstream pair, but I welcome anymore info or opinions). I have no other mods so far other than the SCT tune for 93 octane. THANKS.
