Single or ture duals for a 4.7?

[DjWolf37]

So i cant decide on what to do for my 4.7L. I don't care about sound, just performance (since i need all i can get for this baby V8). its either Option 1. true duals with two with flow cats, and a x pipe and one pipe running on each side, or Option 2. new y pipe with a single high flow cat. Also either way i will be using spintech mufflers and doug thorley ceramic headers. So should i be doing option 1 or 2?????????????????? Oh and yes i can run a pipe on both sides since i am not running the stock gas tank:nana:

I remember Grady saying that he lost ALOT of low end by doing the true duals. But that was with the GiSM headers as well.
