I had to be able to close mine with headers. It was way too loud to drive with them open all the time.

I'm considering buying a new C6 GS with NPP and I'm wondering if I'll be happy with the tone simply pulling the fuse, or if I'll need to think about buying a catback system to get my burble fix.

Yes you do get burbles and pops on decel at low rpms.
