Unlocking Cosmetics

Hello, I am still pretty new to all of this, I currently have DBD save editor, EAC byPass and Cloud Extract downloaded, i have been looking thru the forum finding out as much as possible, how ever i am still unsure the best way to go about getting specific cosmetics and if it is possible to do thru editing my save.
I am trying to get the howling grounds cosmetics (mainly the hound mask) , is this possible with editing my save file? if so, any direction would help. If this is not possible, could someone point me in the right direction on how i would go about getting these cosmetics.

:To mods: if i posted this topic in the wrong place i apologize in advance
