After about 8 months, I'm getting the SES light consistently. I have the Berks HFC and FI SS exhaust. The error code I'm getting is P0430 (below emissions threshold). My local mechanic tells me the the rear O2 sensors have to be replaced since it seems that their voltage reading is stuck. Does this seem likely? Is it something that happened because I have HFCs?

Also I'm considering adding another set of resonators to cut down on the noise a little bit. Does anyone have any suggestions?

Thanks
