catalytic converter

[Nauxcorolla]

does anybody know is it save to remove catalytic converter on a 06 e12 corolla will it trow any fault or anything? 

[FROSTYBALLS]

In the UK removal of the catalytic converter will probably mean an MOT (annual vehicle test) failure. The same may be true of the Irish NCT.

ya i understand that but I will fit it again for mot

If there's an O2 sensor after the converter then you will experience issues, as the car's ECU will be expecting a specific reading from the gases going through the converter. If you remove it, then the gases won't change, and this will throw a warning light.

ya there is a sensor on it but the dummy cat allows a sensor to be put on so will it still trow faults. thansk in advance

[mickburkesnr]

It will keep throwing errors, because the gases aren't changed via a dummy catalytic converter.

If you remove the cat I think you will need to have a bit of work done on your ECU to compensate for it.
