Will High Flow Cats Throw a Code

There is no definitive answer to this question as it depends on the specific vehicle and its emission control system. However, in general, high flow cats are less likely to throw a code than stock cats due to their increased airflow and ability to more effectively remove emissions.

If you’re considering installing high flow cats on your vehicle, you might be wondering if they will throw a code. The answer is maybe. It depends on the make and model of your vehicle as well as the specific high flow cats you’re considering.

Some high flow cats are designed to work with certain vehicles and won’t cause any issues, while others may not be compatible and could trigger a check engine light. If you’re unsure, it’s always best to consult with a professional before making any modifications to your vehicle.

Will a High Flow Cat Still Pass Emissions?

There’s a lot of debate on this topic, but the answer is: maybe. It depends on your specific vehicle and the emissions standards in your area. If you have a newer vehicle, it’s likely that your catalytic converter is already designed to flow more air than a stock converter.

So, upgrading to a high flow cat might not make much of a difference. However, if you have an older vehicle or live in an area with stricter emissions standards, a high flow cat could help you pass emissions tests. In general, high flow cats are less effective at reducing emissions than stock converters.

But they can still help reduce smog-forming pollutants like hydrocarbons and nitrogen oxides. So if you’re looking for ways to improve your vehicle’s emission levels, a high flow cat might be worth considering.

Can Catalytic Converters Throw Codes?

Catalytic converters are one of the most important emission control devices on a vehicle. They help to reduce harmful emissions from the engine by converting them into less harmful gases before they are released into the atmosphere. However, catalytic converters can sometimes throw codes, indicating that there is a problem with their operation.

There are a number of different codes that can be thrown, and each one indicates a different problem. The most common code that is thrown is P0420, which indicates that the catalytic converter is not operating efficiently. This code can be caused by a number of different things, such as a clogged converter, an exhaust leak upstream of the converter, or a faulty oxygen sensor.

If you get this code, it’s important to have your vehicle diagnosed by a professional mechanic so that they can determine the cause and make the necessary repairs. Ignoring this code could lead to further damage to your catalytic converter or other engine components.

Do High Flow Cats Restrict Power?

If you’re looking to increase the power of your car, a high flow CAT may not be the best option. While they don’t necessarily restrict power, they can reduce engine efficiency and therefore result in less power. High flow CATs are designed to improve exhaust flow, which can lead to increased performance.

However, this comes at the expense of engine efficiency, which can ultimately result in less power. If you’re looking for maximum power, a high flow CAT may not be the best option.

How Do I Know If My Catalytic Converter is High Flow?

A catalytic converter is an important part of a vehicle’s emission control system, and it helps to reduce pollutants in exhaust gases. If your vehicle’s catalytic converter is not functioning properly, it can impact the performance of your engine and increase emissions. There are a few ways to tell if your catalytic converter is high flow:

1. Check the engine light. If the check engine light is illuminated on your dashboard, it could be an indication that the catalytic converter is not working properly. 2. Listen for strange noises coming from the engine area.

A rattling noise may indicate that the catalyst inside the converter has come loose and is rattling around. 3. Look for black sooty deposits on or around the tailpipe. This could be an indication that the converter is not burning off all of the exhaust gases correctly, which can lead to higher emissions levels.

4. Take your vehicle for a test drive and pay attention to how it feels and sounds while driving.


Flowmaster Catalytic Converter

If you’re looking for a catalytic converter that will give your car that Flowmaster sound, then you’ve come to the right place. The Flowmaster Catalytic Converter is designed to work with Flowmaster mufflers and exhaust systems to provide your car with the signature deep, throaty rumble that Flowmaster is known for. This converter is made from high quality stainless steel and features a flow-through design that allows exhaust gases to flow freely, resulting in increased power and performance.


If you’re thinking about upgrading your car’s exhaust system, you might be wondering if high flow cats will throw a code. The answer is maybe. It depends on your car and the type of code reader you’re using.

If you have an older car, it’s more likely that the code reader won’t be able to read the higher flow rates of the new exhaust system. However, if you have a newer car, it’s less likely that you’ll have any issues.
