Turbo noise when letting off throttle

Post delete, I am really annoyed by the turbo noise when backing off the throttle.

It sounds like a raspy howl. I put on a 24" muffler and it brought it down by maybe 30%. Still sounds like a 747 when I'm pulling into a campground at 10 pm. No Bueno!

Anybody have an effective muffler or resonator solution?
