Good Evening, It is often that I hear this question by customers at work and I run down a brief list of what happens. If you cut or clean out your converter it will run, the exhaust will be a little louder and you will most likely get catalyst efficiency errors with oxygen sensor codes. And if you have emission testing you will most likely have problems with that as well. In short yes it can be done and yes it will still run. I hope this helps and if you have any more questions please feel free to ask.

It is not legal to do that .also the computer is taking constant readings in and out of the converter for fuel air management,and best performance , if you cut them off you may actualy loose power instead of gaining .welcome to the high tech cars if its clogged something caused it like poor maintenace or age replace them
