Default Roush axleback problem

For a while now my exhaust has sounded like complete garbage when I start it up. A few months ago I took it to Pronto and had them chase down a couple of very small leaks.

It seems to be getting worse and worse.

I notice it most when the car sits for a day or more, very scratchy & almost a high pitch whistle sound coming from it.

After it warms up a bit and I drive it a couple miles it dies off, but when I get to about 2800-3000 rpms I hear it sound like it's vibrating loose.

Car has a catted X and Roush AB's


Opinions?
