No, the vehicle will not only not have more power it will not run properly with converter removed. Secondly it is illegal to remove the catalytic converter.
It will use more fuel if you remove the catalytic converter.
Yes, and it is also illegal to remove the catalytic converter. Your engine will not run properly with the converter removed and will have less power and will use more fuel.
simple answer; no. Only if the engine has forced induction.
If the catalytic converter is defective more than likely the O2 sensor is defective.
Yes, all vehicles made since 1975 have at least one Catalytic Converter and sometimes more.
absolutely it will have more power however it wont pass the smog If it is a 1996 or later model the computer will try to adjust for the incorrect oxygen sensor readings ,due to the missing cat. This can and will hurt power and economy. Plus it is very illegal to remove a catalytic converter.
P0420 is a Catalytic Converter efficiency failer. More than likely you will need a new Catalytic Converter.
u wont pass emission, but nothing u will get more horse power.
If a catalytic converter is indeed bad, it's far more cost-effective to replace it rather than try to repair it
As the catalytic converter emits CO2 and H2O in the air. The gasses absorbe infra red radiation emitted by the earth and re-radiate the energy as heat back towards the earth. So the more CO2 and H2O emitted to the air the more heat there will be. So no, the catalytic converter does not help reduce the greenhouse effect.
Yes. If a coil is bad causing one or more cylinders to not fire, this allows raw unburned fuel to enter the catalytic converter, where it is burned. This can ruin a converter.
It more than likely is the heat shield on top of the converter. It probably has broken loose.
