What is the best way to increase acceleration in a BMW M3?

I recently purchased a BMW M3 and while I love the handling and overall performance, I feel like I could improve the acceleration. What are some options for increasing acceleration without sacrificing too much in terms of fuel efficiency or cost?

One option could be to install a performance chip or software tuning on your engine. This can improve horsepower and torque, resulting in faster acceleration.

Another solution could be upgrading your exhaust system to a freer-flowing one. This can increase airflow and reduce weight, resulting in better acceleration.
