has anyone adjusted their HKS SS BOV on their drag kits? i wanna make mine louder. i get jealous when i hear my cousins greddy typs S BOV. its a nice loud pish. the HKS has a nice PISH to it too but its too damn quiet when youre outside the car. i hear it nicely in the car... and i know my exhaust is loud.. but their has to be a way to adjust it. i heard if you adjust it to much it will affect boost. any suggestions or tech advice on this BOV?

 

i guess no one has...

 

there should be a bolt on top that you tighten, that's how my Type S is.

 

has anyone tried the color inserts that hks offers? i hear they are supposed to change the sound...
