I know the WW compressor wheel will give you more whistle, but really only in the cab.
Is there any was to get more whistle out the tailpipe on a 7.3?
Can you change the turbine wheel on these stock turbos? :shrug:

Another bump for this one...
Somebody's got to know the answer, I mean isn't that the difference say between an 03 6.0 turbo, and a later model 6.0 turbo? The # of vanes on the turbine wheel, right?

I've never seen a turbine wheel for sale alone, so I assume you can't buy one for the 7.3. but that would give you more whistle out of the tailpipe, right?

Anyone know?

later

Yeah i'm straight piped, and getting ready to do the WW and the ATS compressor housing.
I thought that it would only produce whistle inside the cab mostly because it is all done on the compressor side of the turbo. Do you get a lot more whistle out of the tailpipe with it??

so can the turbine wheel be changed in a stock 7.3 turbo? I haven't had mine disected yet.
I'm already decided on the ATS +WW, I was just wondering if there was anything that could be done on that side of the turbo to affect the sound out of the tailpipe.

If there is, then i'll pull the turbo and do all that stuff together, rather than doing those 2 in the truck.
