I dont think its going to be crazy loud. Im running a cutout kinda close to the end of the DP and its not that crazy. I drive around Downtown Chicago like that all the time. Its quiter that an n/a car running open headers.

Heres a vid of a C5 making 786 rwhp on the dyno...no mufflers, twin PTE 67s...3" pipes with turn downs.

The younger you are the more tolerable it is.
Here is a 4" downpipe with a 4" bullet that went to the rear end...

WS6HUMMER, what is the status of your build?? If you dump the DP right under the driver's or passenger's seat it will be louder to you while driving. If you run a 4" pipe out to the tail, then it will still sound killer and will not be as loud in the cockpit.

That would kinda suck if we didn't use our own software, no?
Either way, yes, fully tuned with CMR and flashed with a Predator.
We should have a 4 digit project coming together soon, to be tuned with CMR as well, I will post it up when it is ready.
Here's a link to the thread in the dyno section with all mods listed.
Made 786 backed up by a 783 pull, both at 12 psi...
