JDL header thread is hovering around this one but figured I'd link to my post for anyone curious. I have little to no rasp with this setup. And essentially zero drone. Slightly boomy on startup but otherwise very tame.
I ran a punched out OEM header with this same setup and noticed more drone to the point I couldn't drive with the windows down without headaches and ear pain.
