I keep getting this code , I have dynomaxx long tubes and high flow cats. I know it is the rear o2 senser. What is the best remedy for this? It is only on bank 2. Thanks Tom

I had same problem after LT headers & HiFlo Cats install. We installed a pair* of 02 "Simulators" *(you will soon get another code for the other 02 sensor, because your rear 02 sensors can't handle the increased exhaust flow from the LT headers & hiflo cats)...15 minute job, cost $99....they fool the PCM into thinking everything is OK,so.. NO CODES...did this, rather than tuning out the rear 02 sensors...tuning them out could come back, if PCM is reflashed. The 02 Sims' are forever...(well, almost)

i know many people that will turn off the codes for the rear o2's for less then a pair of sims...usually its best to ask around in your region to see if a fellow vette owner with hptuners or the like can turn them off for a dinner or a few bucks.

Yeah I got tired of that nonsense... I turned it off with hp tuners. It seemed to do it a lot once I got an X-pipe for some reason. Maybe the additional airflow made it trip sooner.
