It's interesting how something as mundane as an exhaust-powered air pump could take control of so many car enthusiasts. Really though, it's not that surprising the deeper you think about it. The intoxicating symphony of whooshing, whistling, and PSSHT-ing directly hits our dopamine receptors. The devotion isn't just aurally based either.
