6.4 exhuast sound change ?

Does anyone have any custom tunes that change the sound of the exhaust. Not looking for a loop tune but looking for something other than the hairdryer sound. I am running a H&S mini maxx if that helps.

Thanks.

Seen some videos of people messing with single turbos and different mm numbers. Can anyone elaborate on that any?

The twin turbos are what quiet it down. The people with singles that you see videos of sound alot more like a 6.0. I wish I could get my 6.4 to sound better without swapping turbo set ups

I've got a 4" downpipe back... I get the "jet" noise, or the Hair Dyer noise... In my opinion there's not gonna be a tune that changes your exhaust sound.. the only thing you can do is actuall tinker with exhaust components.. with that being said I'm assuming that your deleted, so your best bet is to by a muffler.. it will still sound good, won't be obnoxiously loud, and from what I've heard it will help to eliminate that hair dryer noise.. I personally don't mind it.. I like that looks from people

You can actually play with your turbo veins and change the sound a lot. If you have MCC you can put the VGT to wide open at idle and have it go back to normal at 800RPM. This will give you a throaty sound

You can change it if you want at all areas if you prefer, but you may have to change your driving habits. Just unplug your VVT plug and you will see what I am saying. I actually have a tune that I use that has the veins open a lot, while it still has some what of a hair dryer noise, most of it is gone.

Here is a post from Mike Haller:
set the desired back pressure table to 0 psi up to 1k rpm. then set vane position tables up to 1k rpm to 0%. the vanes will kick open at idle then close and resume normal operation after 1k rpm. I did this on my drag truck and it sounds pretty cool.
