I'd say just under and thousand. Got a reply from borla today and they think it's a failing valve. Representative said they should be replacing it under the warranty, just waiting on their reply after I sent them over the original invoices.
No real update on a solution....
After contacting GM one of their technicians said the noise was "normal" and that they are aware of the issue.
I asked them which it was, was it "normal" or a known issue? Its really just a way of them "copping out" and I did t feel like fighting this any longer...

Any ideas?
I've gotten under the truck and the exhaust seems to be secured properly so it leads me to believe its within...

Thanks everyone for your input/ideas!
So i went and did that bolt "hack" on the valve and it didn't really seen to do anything about the noise I'm hearing...
This is after having the entire exhaust swapped out by the dealer a few weeks ago. They said it was the valve making the noise and...
Picked up a 2017 Denali just over a month ago, been hearing a "fluttering"/rattling type sound when accelerating. I'd say it usually happens at about 1500-1700 RPM... occurs when you're asking for a little more speed and usually stops when at cruising speed.
Dealer said it's the sound of some...
