Those are the oxygen sensors. You will might get a check engine light now that you gutted the cats.

If you havent got a check engine light by now you might not get one. If so there is nothing you could do about it. If you delete the code it would just keep coming back.

Hi Filo

I also removed my cat on my CRD, replaced it with a straight pipe. Much better response from the engine as the turbo spools up faster.

I don't get a check engine light, but I have an error code - P2a00. It's the oxygen sensor.

Next week I'm going to flash tune the ECU, and my tuner says he will rectify this error code when he does the tune.

I also put in a smaller/lighter than stock freeflow backbox, and there is a nice deep burble from the exhaust now. But the sound is not noticeable from inside the car, actually only when standing behind the car is the different sound audible.

Hi Filo

Before I put the straight pipe, my cat was also only hollowed out. Then I decided on the straight pipe. It is definately better, plus the diesel consumption also got better.

I have an OBDKey bluetooth adaptor, and use the torque android app.
With these I read the code.
