Not sure about your state laws, but cheapest route is to just cut the muffler off and put a 18inch pipe in. You can check out the sound of mine, and see if thats the kind of rumble your looking for. It not go with the extreme(great reviews).

I think I will go vortex, like I said my uncle will do it for free to promote his business lol. I'll probably go with the single in dual out just don't know how I want the back yet. either behind the wheels with turndows or out the back with tips something like that

Turndowns (dumped before the axle) get really annoying on interatate trips. I have them and theyre good for in town but theyll give you a headache on extended trips

Buy Mud Grapplers. You'll never have to worry about hearing your exhaust again.

Our trucks are really quiet with the four cats, I have true dual straights and it's not that loud until you step on it.
