You need to hook a code reader up to your ECU. Are you running any kind of engine management, because you may be able to get the code that way.
Does your cat have an O2 sensor bung in it?

Bummer. I don't think the vafc has any code-reading capabilities. My guess is that your new cat doesn't do as good of a job as your old one, and the O2 sensor is picking that up...but that's just a guess.
You need someone to grab the code for you so you can tell exactly why that CEL is on.
