What modifications can improve the performance of an Audi A1?

I recently bought an Audi A1 and I want to enhance its performance. I'm not familiar with car modifications so I need some advice on what changes I can make to boost its power and speed.

To increase the horsepower of your Audi A1, consider upgrading your air intake system. This will allow more air to flow into the engine, resulting in improved performance and fuel efficiency.

Adding a performance exhaust system can also improve the power and sound of your Audi A1. Look for a system with larger diameter tubing and high-flow mufflers for optimal results.
