Will Removing the Catalytic Converter Hurt the Engine?

A catalytic converter is a part of your vehicle’s exhaust system. This essentially required component reduces the emissions of your vehicle and is federally required. While your engine can still operate without a converter, it won’t pass emissions tests. A clogged converter can cause your engine to stall. Whether clogged, damaged or removed, find out more about your catalytic converter and why you may need to pick up a new one for a DIY replacement.

What Does a Catalytic Converter Do?

This small component uses rare metals and other materials to act as a catalyst. As your gas engine runs, the exhaust fumes run through your exhaust system, including the catalytic converter, muffler and tailpipe. These fumes include gases that are harmful to your health and to the environment, right up until they hit your catalytic converter.

As a catalyst, the converter turns carbon monoxide, carbon dioxide and other harmful fumes into water and carbon dioxide. If this component is damaged, fumes could escape before the converter or pass through without being properly converted.

If the component is clogged, then your engine may not receive the proper air/fuel mixture due to a buildup of fumes. This can result in a loss of acceleration power or an engine that won’t start at all. You’ll usually see a check engine light, which can point you to a leaking or clogged converter.

How much is a catalytic converter? Check it out online or at your local auto parts store. This component can vary between $100 for your own converter to well over $2,000 to hire a mechanic to replace it.
