Is a Muffler Delete Illegal in California?

If you’re a car enthusiast or simply looking to enhance the sound and performance of your vehicle, you may have considered a muffler delete. However, before going ahead with this modification, it’s important to understand the legality of a muffler delete in California.

In California, the laws regarding mufflers are quite strict.
