hey fellow turboheads! i currently have a ford fg xr6t and am considering buying a BOV but not sure as to which one would suit? I want that classic air release sound and just wondering what the best brand to fit would be? Also are there any adjustments i have to make??

that "classic" air release sound could be any of a number of different sounds, some BOV's sound different to others.

Or having NO BOV, or a blocked BOV for flutter is different again, and for flutter depending what intake you have and what it is made of, and even the size/length and number/type of bends can change the pitch of sound,

also the size of your intercooler has a small effect on flutter sound, larger intercooler will have a slower drawn out flutter, standard cooler will flutter fast.
