California exhaust modification laws?
I am going to get a AWE track edition exhaust for my w205 C450 AMG. I wonder if this exhaust is California legal before I buy it. After installing the AWE exhaust will I still pass the emission test and the vehicle sound tes

My understanding is all cats and sensors have to be as delivered.
