How to increase the performance of my BMW M1?

I recently bought a BMW M1 and while I am impressed with its performance, I feel like there must be a way to make it even faster. Can you suggest any modifications or upgrades that I can do to my car?

First of all, congratulations on your new BMW M1! As for increasing its performance, there are a few things you can do. You can start by upgrading the exhaust system to improve air flow and reduce backpressure. This will not only enhance the sound of your car but also increase its horsepower. Additionally, you can install a cold air intake to allow more air into the engine, which will result in faster acceleration. Finally, consider upgrading your car's ECU to improve its power output. However, keep in mind that these modifications may void your car's warranty.
