How can I increase the horsepower on my BMW M9?

I recently purchased a BMW M9 and while it performs well, I feel like it could use some extra power. Are there any modifications or upgrades that I can make to increase the horsepower on my M9?

First, consider upgrading your air intake system to allow for more air flow, which will increase horsepower. You may also want to look into a new exhaust system for better engine performance.

Adding a performance chip to your BMW M9 can also significantly increase horsepower. Just be sure to do your research and choose a reputable brand.
