I just put modded Z06 mufflers on my 2005 C6 LS2. I have headers, catless X pipe and a G6X3 cam. You can see my sig for the other stuff. I couldn't drive the car since half the body was off and I didn't have the NPP retrofit kit and M2W at the time. Here is what I can tell you though:
With the valves open they are close to, if not as loud as my Stingers were. It's hard to say but for all intensive purposes they are damn loud. Not sure about drone etc since I didn't drive the car. They sound VERY good for sure though. I wedged the valves closed so I could get an idea but it does muffle it quite a bit and I could actually have a conversation near the car. I think most of the drone will be gone when the valves are closed.
I'll have some more info and video once I get the car back in two weeks when the wide body is done.
