CARB Compliant Exhaust Options?

Hey Corvette Fam - I’ve got an LS2 C6 (M6) and I want to get an exhaust for it. However, being in California, I hear it needs to be CARB compliant. I would appreciate any insight as to what my options are.

Is a cat-back out of the question?

Looking for something nice, but not obnoxious.

Appreciate the help!
