Introduction

If you're looking to upgrade your Audi A4 B8's exhaust system, you may want to consider installing a high flow catalytic converter (cat). Not only will it improve your car's performance, but it's also an environmentally-friendly choice. In this article, we'll discuss everything you need to know about high flow cats for the Audi A4 B8.

What is a High Flow Cat?

A high flow cat is a catalytic converter that is designed to allow a greater flow of exhaust gasses through it. This creates less back-pressure in the exhaust system, which in turn can lead to improved performance. High flow cats are typically made from high-quality materials, such as stainless steel or titanium, and are designed to last longer than factory catalytic converters.

Why Upgrade to a High Flow Cat?

There are several reasons why you may want to upgrade to a high flow cat for your Audi A4 B8. Firstly, it can improve your car's performance by increasing horsepower and torque. Secondly, it can improve your car's sound by creating a deeper, more aggressive tone. Finally, it's a more environmentally-friendly option than the factory catalytic converter, as it allows for a greater flow of exhaust gasses.

Installation

Installing a high flow cat on your Audi A4 B8 is a relatively simple process that can be done at home with basic tools. However, we recommend having it installed by a professional to ensure proper fitment and performance. The installation process typically involves removing the factory catalytic converter and replacing it with the high flow cat.

Cost

The cost of a high flow cat for your Audi A4 B8 will vary depending on the brand and material used. However, you can expect to pay anywhere from $300 to $1000 for a high quality high flow cat. While this may seem expensive, it's important to remember that it's a long-term investment that will improve your car's performance and sound.

Brands

There are several brands of high flow cats available for the Audi A4 B8, including Magnaflow, Borla, and AWE Tuning. Each brand offers different materials and designs, so it's important to do your research and choose the one that best fits your needs and budget.

Legal Issues

It's important to note that installing a high flow cat on your Audi A4 B8 may not be legal in all areas. Some states have strict emissions regulations that require the use of a factory catalytic converter. Before installing a high flow cat, make sure to check your local laws and regulations to ensure that it's legal.

Maintenance

Maintaining your high flow cat is important to ensure that it continues to perform at its best. We recommend cleaning it regularly with a high-quality catalytic converter cleaner, such as Cataclean. Additionally, make sure to have it inspected by a professional at least once a year to ensure that it's functioning properly.

Warranty

Most high flow cats come with a manufacturer's warranty that covers defects and premature failure. However, it's important to read the warranty carefully to ensure that you understand what is covered and what isn't. Additionally, make sure to choose a reputable brand that offers a strong warranty to ensure that you're covered in the event of an issue.

Conclusion

While it may seem expensive, it's a long-term investment that will pay off in the long run. Just make sure to do your research, choose a reputable brand, and have it installed by a professional to ensure that it's done properly.
