Take away its ice cream. 
You gotta open up the intake and exhaust, especially the exhaust. These turbos don't make all the compressor noise that powerstrokes do, but when you open up the exhaust the turbine sure does sing!

Yep. Open the exhaust and you'll get a good rush. Not the high-pitch whine of the more modern engines... its more like the sound of a wicked wind storm, or a jet engine at low throttle. A little more "airy".
Got that sound when my exhaust fell off on a rough trail this winter. Unfortunately, with no muffler these trucks really roar at higher RPMs. Then I went Banks turbo and now I have that high-pitch whine. Wish I had it screaming like our scooptrams at work do, they have Detroit diesels and the turbo is almost all you can hear.

Try opening Your rear slider. You'll get a better idea of what peeps on the street are hearing.

Also, the more pipe you add, the less turbo sound you will hear.
I have the ATS upgrade kit (3" elbow and downpipe), at the end of the downpipe I have about 2 feet of 4" pipe, a Walker 21172 muffler, and a 4" bend serving as a turnout. It sounds great and is not as loud as you'd think, in fact it's not even bad on the highway with the windows closed.
