Q:I have a 2020 mustang GT 5.0 premi coupe. Bought the car with missing cats does this item fit and does it take 2cats? Show Less
Richard N.
A:BEST ANSWERHi Richard, I'm pleased to assist you. No, this cat does not fit the 2020 Ford Mustang GT Premium 8 Cyl 5.0L. We currently only have the Federal emission direct fit driver-side cat compatible with the vehicle. Check the Vehicle Emission Control Information sticker, usually found underneath the hood, to see if it matches the emission control specifications. Federal emissions (46-state) stickers will simply say, "This vehicle conforms to U.S. EPA regulations," whereas California-emissions (50-state) vehicles will say, "This vehicle conforms to U.S. EPA and State of California regulations." If interested, use the link below to place an order while supplies last. Your order will come with a 30-day post-purchase price match guarantee. I hope this is helpful. Merry Christmas from CarParts.com! https://www.carparts.com/details/Ford/Mustang/Dorman/Catalytic_Converter/2020/GT_Premium/8_Cyl_5-dot-0L/RB674499.html?can=CPGG4850_CSQA_20221223 Show less

Clever Ways to Care for Your Mitsubishi Lancer Catalytic Converter

To protect the environment, your powerful Mitsubishi Lancer is equipped with a catalytic converter. It acts like a filter that controls the emissions produced by your vehicle. Found on the underside of your car, your Mitsubishi Lancer catalytic converter ensures that the harmful gases from your vehicle get neutralized before they get expelled into the environment. Here's how you can keep the cat con in good shape:

  • Always have the correct oil and fuel in your car.

Although it's cliché to tell you that you should use only the correct fuel and oil for your vehicle, it's still an important reminder, especially when it comes to your catalytic converter. Take note that it's really easy to accidentally put the incorrect fuel into your car; in fact, at least 150,000 car owners fill their vehicles with the wrong fuel every year.

  • Read the instructions before using a fuel additive.

Whenever you plan to use a fuel additive in your vehicle, make sure that you read the instructions first. This allows you to scrutinize the additive, and assess if it's suitable for use with your Mitsubishi Lancer catalytic converter. If you're not sure of the instructions, consult the product manufacturer.

  • Don't try to bump start or tow your vehicle.

Bump starting your car can make the unburned fuel in the system to be injected into the cat con. This, in turn, has a tendency to make the monolith overheat and melt down. Be sure that you avoid bump starting your car to prevent damaging the cat con.

  • Avoid driving through fords, deep puddles, or parking on areas with heavy snow.

Since the cat con operates at particularly high temperatures, driving through deep puddles or parking on heavy snow can damage the converter. Splashed water or snow immediately cools down the cat con upon contact. When this happens, the steel shell cools faster than the monolith, making the monolith vulnerable to getting crushed as the steel shell contracts.

  • Refrain from using exhaust paste in front of a catalyst during fitting.

When you're fitting the cat con, make sure that you don't use exhaust paste. This type of paste can harden and break down in chunks, leading to monolith damage. Plus, the exhaust paste can also obstruct the monolith.

As a vital component of your car, you need to ensure that the catalytic converter is in good working condition at all times. Since they are located on the underside of your vehicle, they become at risk of getting damaged by external factors such as impact from road debris. Your Mitsubishi Lancer catalytic converter can cause internal damage to the engine as well. So to identify a cat con that needs replacement, below are some of the symptoms you can use for reference:

Your car's fuel economy suddenly goes bad.

When the cat con is busted, you'll immediately notice a change in the fuel efficiency. The most obvious sign you'll notice would be a reduced gas mileage. This means that your vehicle consumes more gas than usual, and this can lead to huge costs if the cat con is the sole root of the problem.

To restore your car's fuel efficiency, you must change the broken cat con as soon as possible. You can do it yourself in just a couple of minutes, and you only need to use basic car repair tools. But if you're not familiar with the exhaust system of your vehicle, then you can simply bring your car to the nearest auto repair shop for a catty replacement.

The engine starts misfiring.

Your Mitsubishi Lancer catalytic converter can overheat whenever your engine system misfires. This occurs when the fuel mixture becomes extra rich, which in turn, allows raw fuel to enter the cat con and get fired up. Since the temperature in the catalytic converter now exceeds the normal operating temperature, the catalyst components inside the cat con can melt.

Keep in mind that your vehicle's fuel is supposed to burn only in the combustion chamber. It shouldn't reach the exhaust system, and ignite upon contact with the converter.

Your vehicle's carbon emission has increased.

If the cat con in your car has gone bad, chances are, the chemical mechanisms inside have been contaminated. This is usually a result of adding substances such as antifreeze or motor oil in your vehicle. Take note that these chemicals can prevent your car's catalytic converter from functioning properly.

With the increase in carbon emissions, you put yourself at risk of getting fined for emitting illegal amounts of emissions into the environment. Plus, it can also cause damage to the whole exhaust system if left unattended.
