I don't remember who did a video, it was either TopCorey or ResultsMayVary on YouTube but they described why the 6.0's turbo made such a distinct whistle. They both use SPE parts so it might be worth giving those guys a call. It had to do with number of vanes on the turbo. In short, it's possible to make a 6.7 whistle like a 6.0 but will also very likely require the removal of the awesome hardware mandated by the EPA.
Are you trying to get that distinct 6.0 chewbacca growl or the loud 2003 6.0 turbo whistle?
If it's the whistle you are going for, a 10 blade turbine wheel is what you need. KC Turbo and Ryan's Diesel Service both make a turbo for the 6.7 Powerstroke utilizing a 10 blade turbine that should make it whistle.
If you want that chewbacca growl, that I have no idea how to achieve.
