| One of the more noticeable improvements you could make for your vehicle is to put a more aggressive gear ratio in it. Do you happen to know what the stock gearing is?
Intake, exhaust, and programming (chip) typically will not provide a huge improvement over stock. The associated sound will make you think you're going faster, but on BMW's as I'm sure you know the factory did a great job already.
