When you remove the cat you will have a sensor which comes out of the cat pipe. WHatever type of de-cat replacement pipe you are using there SHOULD be a place to put this sensor back in.

Without a place for the sensor your going to get an error light. THe only other way i could think around this is to remove the sensor, figure out the signal (.i.e voltage) that the snsor gives out when its in normal mode and fit a rsistor or something in its place to provide a working signal to trick the ECU into thinking the sensor is still there.
