How to make my Toyota Tacoma loud?

I have a 2005 Toyota Tacoma. I'm going to be putting an aftermarket exhaust on it soon. Don't know what to get, because I want a particular sound from my truck. I want it to have a deep loud rumble. Like when I start it you know it's after market and it just sounds mean. But I want it to be legal so no straight pipes or anything. So what do I go with? Flowmaster, cherry bomb what? Thanks for the help
