I'm considering deleting the CATS on the car, and on my other cars the code set off by the rear o2's doesn't do anything other than set the SES light, no performance damage, no crazy fuel dumping etc. I was wondering if it was the same with this car? I'll order sim's but they won't be here until next week so I was curious if it will just set the light, or if it does change fuel/timing tables in the PCM. Sorry if it's a repost, I searched and only found 1 reference that eluded to it not doing anything other than set the light, but nothing finite. Thanks!
