As part of a car's exhaust system, the catalytic converter helps to reduce air pollution. You will not harm your engine or your car in any way by driving without a catalytic converter.
What happens if you don't have a catalytic converter?
Your catalytic converter is named as such because it converts toxins into less harmful byproducts, such as water vapor and carbon dioxide. Without this component, your vehicle will no longer be filtering and reducing harmful emissions, including hydrocarbons, nitrogen oxides, and carbon monoxide.

How do I know if someone stole my catalytic converter?
Although it might not be immediately obvious, you may be able to tell that someone stole your catalytic converter if your vehicle sounds extremely loud after you start it. You may also notice that your Check Engine light is on, and you could get a headache from the increased emissions.
How does a car sound without a catalytic converter?
You'll notice a loud rumbling or roaring sound when you turn on the engine if your catalytic converter is missing. This sound gets louder when you hit the gas. The exhaust is not working correctly, so the vehicle also drives rougher than usual, often with a sense of sputtering as you change speed.
How much is a stolen catalytic converter worth?
Police say thieves can get from $100 to $150 for each converter. The insurance group counted just 3,969 reports of stolen catalytic converters in 2019, more than 17,000 in 2020 and more than 52,000 last year.
Will removing catalytic converter hurt engine?
Since the catalytic converter places a strain on the engine with its constrictive design, it must work harder to achieve the same energy than it does without the device in place. Removing it lessens this burden, creating a net effect where the engine can perform significantly better without working as hard.
Is it worth fixing a catalytic converter?
Is it worth replacing your catalytic converter? Due to the cost involved, replacing your catalytic converter should be considered a last resort. This is especially true if your car is very old, has a lot of miles on it, is not particularly reliable, and you live in a state with tough smog laws.
How long is a Catalytic converter warranted?
Be warranted for 5 years/50,000 miles, and cover the cost of parts and labor. Be compatible with OBD catalyst monitors. This includes making sure converters won't cause false catalyst codes, while also making sure that the OBD system will continue to set a catalyst fault code if the aftermarket converter fails.
How long do you have to keep a copy of your catalytic converter?
The installer must file and maintain a copy of all documentation for a period of at least 4 years from the date of installation. ATTENTION: Under California regulations, it is illegal to install a catalytic converter based solely on physical shape, size, configuration or pipe diameter.
How to replace a converter?
To prevent a recurrence of emissions-related problems, the following steps should be taken prior to replacing a converter on a vehicle equipped with an OBDII system: 1 Prior to installation of a new converter, retrieve all PCM (Powertrain Control Module) trouble codes and perform required repair procedures for any stored codes. On some applications, manufacturers may have issued Technical Service Bulletins indicating that re-flash updates of the PCM may be required to resolve emissions problems. 2 Repair all exhaust system leaks. 3 Check O2 sensor operation to ensure vehicle is in proper fuel control.
How long is the warranty on an OE converter?
