Corsa NPP Valve Not Fully Closing?

In stealth/closed mode one muffler is still quite loud and sounds like the valve is not fully closed. I can't figure out why /what the issue is. Have chopped the valve connector butterfly things years back but now the rattle has returned when valves are closed and it is much louder than it should be in "closed" mode. Has anyone found a way to address/fix?
