How do you make a car louder legally?

What are some ways that I can make my car louder legally? I live in California, and there are laws about how loud your car can be. I want to make mine louder, but I don’t want to make it so loud that I get into trouble.

Answer
Loud cars can be fun to drive—but you should still keep it within reason. Here are a few ways that you can legally make your car louder in California:
  • While you can’t remove your muffler entirely, you can get a smaller muffler to make your car engine louder.
  • You can also get a larger engine to produce more noise. This is a more expensive way to go, but it certainly works.
  • You can legally install an aftermarket exhaust system as long as it does not cause your car to exceed 95-decibels.
In general, you should be okay as long as you don’t exceed 95-decibels of noise when driving. To put that in perspective, 95 decibels is about as loud as a revving motorcycle engine.
