How to increase horsepower in a BMW M3?

I recently purchased a BMW M3 and I feel like it could use more power. Are there any modifications I can make to increase its horsepower?

One way to increase the horsepower in your BMW M3 is by installing a performance exhaust system. This will allow better airflow and increase your engine's power.

Another option is to upgrade your car's intake system. By replacing the stock air filter with a high-performance one, you can improve the engine's intake and increase horsepower.
