Can I Hollow Out a Catalytic Converter?

Hollowing out a catalytic converter is another modification car enthusiast do to increase their vehicle performance.  It involves gutting the internal catalyst (the catalyst is what makes the converter “catalytic”), which reduces harmful emissions from your vehicle’s exhaust. 

As a result, you enjoy enhanced engine performance. But when you remove this stainless steel catalyst, you violate illegal emissions regulations. This can lead to exhaust leak, harming the environment and human health. 

Additionally, it lacks the heat shield against extreme temperatures, potentially damaging your engine. So, hollowing out a catalytic converter is an unwise choice.

How to Clean a Clogged Catalytic Converter Without Drilling Holes 

Some car enthusiasts think drilling holes in the catalytic converter can remove the clogging. Well, As we already know, drain holes are not the right solution, whatever the problem is! 

If the problem is a clogged converter, the simple solution is cleaning. You can clean it with homemade cleaner or buy chemical-based cleaner (specifically designed to break down carbon deposits). 

Catalytic cleaning additive is readily available online or near auto arts shops. Just go and buy one, it won’t cost you a fortune (15$-20$). 

Let’s learn two simple cleaning methods you can follow if you have a clogged catalytic converter. 

Catalytic Converter Cleaning Method Without Removing

If the clog is minor, you don’t have to remove it; you can clean it without it. You must ensure the fuel tank has less fuel (4 gallons or 15 liters). Then follow the below steps.

• Unscrew the bolt and remove the cap of your gas tank. Put a nozzle into the tank to avoid spills. 
• Now pour the cleaning solution into the gas tank and screw back the gas tank cap. 
• It’s time to drive the car; when you drive the car, the cleaning solution will run through the engine and catalytic converter and clean the clogs it has inside. 
• Drive for at least 15 minutes or until the fuel tank is empty. 
• Reach to a nearby fuel station and fill the fuel tank as usual. Your car catalytic converter is now free of minor cloggings and ready to drive again.

You can follow this process after you drive 8,000km to keep the converter free of any build-up and in good condition.

Catalytic Converter Cleaning Method By Removing

Cleaning catalytic converters by removing them is also simple and more effective. You can use homemade or store-bought (pb blaster), any cleaning solution, or whatever you have available. 

• Let’s make a homemade cleaning solution by mixing laundry detergent and water in a large bowl or bucket and keeping it aside. You can add a few drops of ammonia for better results. Or take the store-bought cleaning solution.
• Now remove the catalytic converter from your vehicle and soak it in the cleaning solution overnight. 
• Or if you want to use store-bought cleaner, you can’t soak the catalytic converter as it will cost you a lot. So you can plugged cat with a pressure washer or garden hose with a nozzle. 
• Spray inside the catalytic converter through both ends on the lowest setting.
• Continue spraying until all the buildup is broken and comes out or you are satisfied.
•  Once cleaning is done, use a clean microfiber cloth or rag and dry the catalytic converter. Or, if you have enough time, let it air dry to avoid any rust.
