The reason why a single exhaust system cannot be transformed into a true dual exhaust is because of smog regulations. In order to make your performance exhaust system street legal, exhaust manufacturers cannot tinker with your factory-installed catalytic converter. They cannot add a new converter, and they especially cannot remove one. Since switching from a single exhaust to a true dual exhaust would require adding another catalytic converter into your exhaust equation, it would make the system not street legal.
