Not sure of the smog standards in your state.
In CA we have strict smog requirements (but we also have the most cars on the road)
Last time my truck failed the smog test and I had to replace the CAT, O2 Sensor and EGR valve in order to pass. This is why I won't even mess with the emission components on my vehicles.
