The only way of changing the sound would be to extend length of the pipe or maybe add a tiny silencer on it which would defeat the purpose of having it by adding more weight to your car and etc, or recirculate it back into the exhaust(BEST OPTION).
I have a JDL Autodesign kit with a Open dump, It doesn't open up till 9 Psi but that puppy screams when its open, I would suggest moving to a bigger spring in your wastegate so you're not always opening it up after giving it gas. You can even get a Electronic boost controller after moving to a bigger psi spring so you can limit the amount of boost you run, but I think the lowest setting on a boost controller is always your spring's rating.
just my 2 cents.
