i have a hks sqv ( purple fin ) and a baileys dump valve sitting around not doing anything. the baileys came off my 95wrx , has a blue trumpet but there is a deep scratch on the trumpet, it works perfectly fine, i will try get a pic.
also have a hks sqv

all works fine, i bought it without a fitting kit but got offered one with, so fitted that and this is spare.
if anyone is interested pm and make me an offer

 

pics of dump valves, the baileys dv has a few marks on it, and a little cut in the outside of the trumpet, i have no idea what it was as it was on there when i bought the car, doesnt affect it at all. and the hks is also in perfect working order
any offers as they are sitting around gathering dust
