It may be against federal law, but in my county In WA state we do not have emission laws. In Skagit county you can legally sell a vehicle without a catalytic converter. Now is it still illegal to remove yes, but how will you get caught. No vehicles are ever emission tested in this county and when I go to sell or even trade in it wont matter.
And a cel can be avoided with a Sensor Simulator.
And I though the Smog pump goes into the headers right before the Cat.Thats why UDR had to develop new headers!
