2007 Chevrolet Impala LS exhaust?

Yea I may be getting an 07 Chevy Impala LS. But the thing is that i want it to have a muscle car sound with its 3.5L V6.. Does anyone know of any great mufflers to get for it. I have checked Flowmaster, Magnaflow and Cherrybomb cause those are good brand names. Are there any other good names? Serious answers only!
