well my dads got the 06' 6.0 with exhaust and yes it does sound bad as f*ck but personally the sound of my obs 7.3 4'' straight pipe drives me up the wall! (in a good way)

it prolly could be done but would be real hard to get the computer to operate the VV's and it would be kinda dumb and useless.....

The VGT is not as large on the turbine section. I don't think it will move enough air for the larger 7.3, especially if it is tuned. The factory turbo does a good job as far as spooling quickly at low rpm's, that would be the only advantage in using a VGT. The factory 7.3 turbo will not get out of the way in the high rpm's (after 25 psi boost the Detla P goes to sh!t the back pressure climbs faster than the boost builds. You hit the top end of the compressor's efficiency. Thats when you burn up a turbine or piston.)

If you want whistle get an H2E or other T4 type and you will have all the turbo scream you can stand. I am getting pretty tired of hearing mine already, maybe not quite yet! LOL
