Dynomax VT mufflers

I have a set @ 2-1/2 off set in, center out. I myself didn't like the sound or the level of it on my mostly stock 5.9 with 1-3/4 headers into a true dual exhaust.
No noise from the flapping valve. I was looking for something pretty quite for my cruiser and ended up with Dyno Max Super Turbos.
There just sitting around collecting dust now.
