How do I increase the horsepower in my BMW 8 Series?

I recently purchased a BMW 8 Series and I love everything about it except for the lack of horsepower. Are there any modifications or upgrades I can make to increase its overall power and performance?

One option to increase horsepower is by installing a performance chip. This will optimize your engine's performance and can add up to 50 horsepower.

Another option is to upgrade your exhaust system to one with less restrictions. This will allow for more air flow and can add additional horsepower.
