There is no best, it depends on what you want your truck to sound like. Do a search on youtube and see which one you like better. I'd recommend getting a 3.5" downpipe; if you are planning on getting a turbo and injectors get a 4" downpipe.
My 06 has a 4" turbo back that's straight piped and sounds great. It is loud anytime over 2500 rpm but cruising down the freeway you hardly know it's there.
