Removing Cat

Ok i know that it is against the law in the USA to do this for emission control purposes.
Here in South Africa we dont have that strict laws on emission control.
What all must be done to ECM and or o2 sensors to avoid engine light coming on if the cat is removed
Is there a by pass procedure available for the down stream 02 sensor that avoids error codes

ZZP sells an angled o2 bung that goes in line with your downstream o2 sensor and turns off the engine light. You will suffer poor gas mileage though. Otherwise, you would need an ECM tune.
