so i was really confused and just gutted them.

i still have the cel light on and would really like this to turn off

all help will be much appreciated as nothing like this is available in the uk

thanks

Did you clear the code or reset your ecu yet?

OK so I just installed 2 CEL deleter (90 degree defoulers),reset ECU, and my p0430 is still on. I can go to lexus again and check the code, but I suspect it is still bank 2. What you you suggest my next move be? Just take the car back to stock exhaust w stock midpipe? Or should I go ahead and replace the O2 sensor(s). If so, which one, or all?

Best
