How much horsepower does removing a catalytic converter add?
It is theoretically possible to gain 15 horsepower in total from the removal of the CAT. If your engine's backpressure is decreased, you can gain more horsepower from that engine. The size of your engine influences this. Even doubling the gains from removing CAT can occur when you take your car to a tune once again.Feb 11, 2022

Your car may exhibit symptoms ranging from a slight lack of power and a noticeable loss of fuel economy to a dreadfully sluggish running engine or even a no-start.
What happens if a converter is intact but not working properly?
What about a situation where the converter is intact but not working properly? Well, that will obviously cause your vehicle to fail emissions testing. If the powertrain control module’s catalyst monitor function determines a monitored converter’s O2 storage capacity has deteriorated, a diagnostic trouble code will be stored.
What happens if you remove a catalyst?
If that catalyst is removed, it will always cause the vehicle to fail emissions testing.
How many light off converters are there in a four cylinder engine?
Six- and eight-cylinder engines will have two of these light-off converters (one for each bank), while four-cylinder engines will have only one . And for each light-off catalyst, there is an O2 sensor monitoring the exhaust stream directly behind that catalyst.
Can you drive a car without a catalytic converter?
Vehicles can be driven without a catalytic converter. There are vehicles in non-emission testing areas that have had their catalytic converters removed, but removing a cat-con is against the law in every state, even those that don’t enforce emissions standards.
Can you drive a car with a catalyst that has failed?
Typically a catalyst that has failed so that it affects the way the vehicle performs deteriorates slowly enough that it may not be noticeable at first. Some people will ignore a mild loss of power and/or even an illuminated check engine light and continue to drive until the failure becomes severe. The point is that if the converter is simply suffering from a decline in efficiency, you can continue driving without having to worry about your car breaking down. But you will, in states where emissions testing is required, eventually need to have repairs done.
What Does a Bad Catalytic Converter Sound Like?
Mainly, a bad catalytic converter makes a rattling noise as you drive. In some cases, if the converter fell off the exhaust pipe, you’d hear it scratch on the pavement as you drive. The rattling you hear is coming from the scattered honeycomb meshes inside the bad converter.
