Exhaust Pipe Size ?


I'm looking to put other mufflers (Magna-Flow/Flo-Master etc) on my C6, until I can save enough $ to get an entire system; Long tube Headers, Hi-Flo Cats and back. The stock C6 system is too quiet for me. I'm want loud, deep, throaty. Not obnoxious. On the Magna Flow site I see different sizes. And off-set designs. Any recommendations i.e. is a 4x8 deeper sounding than a 6x9 etc. Is the single in/dual out better. Magna Flow vs Flow Master?
Appreciate any help on educating me. Thanks. JT
