10. Loud Exhausts
Yes, it’s true that a powerful car needs to have a distinctive and strong exhaust sound. There is no better sound than a raspy V8 on idle. And while a big part of the automotive culture is about the loud exhaust pipes, it looks like the insanely sounding muscle cars are going to be extinct. That’s because most states forbid loud exhausts and ask manufacturers of such systems to tune them to legal decibel limits. It is possible to have a quality-sounding exhaust powerful enough to let you know you are in a fast car. But they can be quiet enough, so they don’t wake up the neighborhood or start car alarms.
One of the major concerns in urban areas is noise pollution, and much of it comes from cars and other vehicles. So, to keep the noise levels down, police are cracking down on homemade straight pipe exhausts that are louder than approximately 90 decibels.
