Is it a metallic rattle noise? I think I have the same issue. My valves are spring loaded

I have this exhaust rattle happening for the second time. Sound terrible. The first time, my whole NPP dual-mode exhaust was replaced under warranty. Now, the dealer says its $2600 to fix. I like the NPP exhaust, but not that much, and I don't trust it not to break again. The service writer said it's a bad valve, but the technician had gone home already, so I have to wait until next Tuesday to find out if my failure is part of the adjustable NPP system.
