Also, you'd need to get an office in Delaware to not mandate a foreign registration in California which still involves the taxes. Getting an office in Delaware is pretty expensive but it's about $400 cheaper than California franchise tax. They assess their own but it still works out lower.
Edit: Nevermind, they still tax you on that. I don't condone tax evasion, but Wyoming doesn't track the owners of a corporation.
"Piercing the corporate veil" is different. Google will be helpful if you're interested, but basically if you run a company don't do shady shit -- don't commit fraud or gross negligence, and respect the separation between company and personal finances. Otherwise you may lose the protection of the corporation (the "limited liability" part of LLC) and become personally liable if things go bad.
