There are many reasons for you to take your car to make some repairs. You might not be able to drive anymore because of broken brake pads, starting issues, or something else. No matter the case, it’s essential for you to get it fixed as soon as possible because that can keep your car in good condition and prevent any further damage.

For example, the catalytic converter is a crucial part of the vehicle emissions system. This component converts toxic fumes into less harmful gases. The process also contributes to better fuel mileage and fewer pollutants released into the environment.

What happens when a damaged catalytic converter is not fixed?

The actions necessary for the proper functioning of this part include ignition of fuel mixture with oxygen present in exhaust gases, which leads to chemical reactions between carbon monoxide and oxygen.

If necessary repairs are not done, this system will soon stop working correctly. Another problem you might experience is the lack of power when accelerating your car. This happens because the catalyst uses too much fuel for chemical reactions.

The same issue can also be caused by some problems with O2 sensors informing the engine control unit (ECU) about how much oxygen is present in exhaust fumes before or after the catalytic converter. If these parts aren’t replaced immediately, this may lead to severe damage to other components like starter, battery, alternator, and more breaking down completely.

Besides these issues, you should know that breaking down the catalytic converter will make it difficult for you to pass inspection. Repairing or replacing this part is a good idea to ensure your car will run smoothly on the road. For more information about catalytic converter replacement, contact a professional mechanic.

Tips to fix catalytic converter

Catalytic converters are installed on vehicles with an internal combustion engine to reduce toxic elements released into the environment. They accomplish this by changing harmful emissions into less harmful substances before they’re released into the air.

The process starts when gasoline is burned in your vehicle’s cylinders and creates exhaust gases consisting primarily of carbon monoxide (CO), nitrous oxide (NO), unburned hydrocarbons (HC), and oxygen (O). The catalytic converter contains both precious metals and ceramic granules. The heat from the exhaust gases causes the metals to become active and release a chemical reaction. This reaction changes the harmful emissions into mainly carbon dioxide (CO2) and water, much less toxic.

It’s essential to have your catalytic converter inspected regularly. Not only will it let you know how well it’s working, but it will also help you avoid vehicle breakdowns that an overworked catalytic converter could cause.

If your vehicle suddenly develops power problems or misfires when you step on the gas pedal, there’s a good chance that your catalytic converter has failed and needs to be replaced.

If you notice a puddle of liquid under your vehicle after having driven it lately, there is a chance that your catalytic converter is leaking and needs to be replaced. If you’ve noticed a change in the sound of your engine, mainly if there’s a noticeable lack of power when accelerating, this could also indicate problems with your catalytic converter.


It would be wise for you to have your catalytic converter checked as soon as possible if you notice any one or more of these symptoms. You should make an appointment to take it to a mechanic specializing in exhaust systems for proper testing and replacement recommendations.

The cost of replacing a defective catalytic converter when clogged will often come close to what it would cost to replace the entire exhaust system. That makes repairing it relatively economical since you won’t have to buy new hangers or clamps either. The labor is relatively simple since there are usually only two bolts to remove.

If you find yourself in this situation, your mechanic will most likely be able to replace the catalytic converter with a fully operational one by cutting out the bent section and welding it back together. These repairs require little skill so that most mechanics can complete them in less than an hour at a minimal cost.

However, suppose your catalytic converter cannot be repaired or replaced. In that case, your mechanic may suggest that you have it replaced with a universal model that’s designed to look aesthetically pleasing. This type is typically constructed from stainless steel. It comes pre-packaged with new mounting hardware for ease of installation on virtually any make or model of vehicle on the road today.

It’s important to remember that if your catalytic converter has failed, you risk polluting the environment as well as endangering the health of those who ride in your vehicle with you. In most states, it is illegal to drive a car that emits lower than average amounts of toxic substances, so make an appointment for repair or replacement immediately.
