I want the dump valve on my s2 Rs turbo to be as loud as possible . I currently have a forge fast-road item, which i believe is a group 'a' or summat (or did i just make that up-im not sure) but its not quite as loud as the bailey i had on my old rst. If anyone would like to swap my one for a baileys then let me know, also will it be louder if i take off the foam filter? Or will it ruin it? P.s Padvg or whatever i know your views so don't have a go at me!!
