Stay stock until you can prioritize what you really want.

We have quite a few customers that go the headers with stock catback route. This provides the performance without the sound. I've done the same for some of my own vehicles.

Dynatech SuperMAXX header with hiflow cats and Corsa Sports, great sounds. Putting AFR 225 heads and a 224 228 114LSA cam with a tune on the C6 a week from today, can't wait to hear what it will sound like, forget the additional pick up and goooooooooooo!

Someone here bought the C6 Flowmaster system - they hated it. Lots of resonance.
Agree with others - if you want max performance with little increase in sound level - go with headers and keep the OEM cat back exhaust system.

Maybe this will help. Below is a link to my C6 with Dynatech SuperMaX headers bolted up to the stock mufflers.
