    P0420 for cat efficiency would need the extender on the secondary sensor (o2 sensor) downstream from where the cat would be. the front sensor is your AFR sensor and you do not want to be tricking that one as your ECU is adjusting fuel in closed loop fueling based on what it's reading. How's your car been running?

      I haven't had the brz for almost 2 years now but it ran perfectly when I had it. I keep getting calls from subaru saying that it needs to be fixed so I have no idea what the new owner is doing to it lol

    Might be a little late but when you reset the ecu put the car in accessory mode for like 10 seconds before actually starting the car. it gives the throttle body enough time to calibrate and it should start right up. Usually it will crank for a couple seconds if you dont wait because of the car trying to calibrate but if you wait and then start it, it should start like normal.

    I know the Catted headers are ridiculously expensive right now and that they've doubled in price since I put a set on my '15 BRZ back in '17, but they do keep the CEL from lighting up my dash board.

      @@doggofrs9651 Mine generated a CEL code twice. When my UEL header was originally installed the mechanic sheepishly admitted that he broke one of the O2 sensors. He plugged it, had me order another from Rock Auto, and installed it for no extra charge, just the inconvenience of have to come back a week later. I had to drive around for a week with a CEL.
      The second CEL happened when I was caught in a sudden torrential downpour in congested city traffic. I was in a curb lane and water was not draining. I was forced to drive through a deep puddle and at least one of the O2 sensors shorted out. When it dried out I reset the code either through my OBD2 scanner or my Open Flash Tablet. I've not had a problem since.
      Check your O2 sensors, wires, and connectors.

      Yup, me personally I cleared my codes as soon as it threw a CEL and it popped back up after driving about five miles. But the defouler is only really necessary on catless applications.
