What is the best way to increase horsepower on an Audi A3?

I am looking to add more power to my Audi A3, but I don't want to break the bank. What are some cost-effective options for increasing horsepower?

One of the most effective ways to increase horsepower on an Audi A3 is by adding a performance chip. This will optimize your engine's fuel-to-air ratio and can result in a significant horsepower increase.

Another option is to upgrade your exhaust system. By installing a high-flow exhaust, you can improve your car's airflow and increase horsepower.
