As for the deepness of your exahust, you're never going to soun like a big ole V8, but you can make it sound somewhat decent, better than stock anyways. For that trick you'll need dual exhaust for sure, and when you get a dual exhaust kit, make sure it's no bigger than 2.5" piping. It can go to 3" at the tips and that will actually give it a little deeper tone too, but just to warn you don't be looking for the signature V8 rumble. I'm not sure about LT being legal in Cali because I don't need to worry about that. But for sure you'll need cats. When looking for an exhaust system you'll need to make sure it has a C.A.R.B. legal tag on it.
