I have for sale a go fast bits stealth fx blow off valve in excellent condition with a wrx/sti flange. It has a port for venting to atmosphere and one to run back into the recirculation hose. It is very easy to adjust from full vent or full recirculation or anywhere in between to split where the air goes. The spring tension is also easily adjusted by turning the top cap and the vacuum nipple part also rotates around. These are very sought after blow off valves and cost over $400 new. I'm looking for a louder bov so I will trade this for a MINT Turbo Xs Type H/RFL BOV with the wrx flange plus some cash or a HKS ssqv bov with the wrx flange.
