True dual or dual outs?

[gabeherndon]

I am wanting to put on a 40 series flowmaster on my '99 silverado (5.3) and I just want to know which will sound better. A single in dual out with turn downs OR true duals with turndowns? Of course single in dual out is cheaper than buying two mufflers but I want it to sound good and mean!:devil:

you really wont get much diff at all in sound on a stock truck, nor do you need it power wise. I'd say dual out of one muffler.
