I'm thinking of installing one of the WRX Stealth FX dump valves as seen on http://www.scoobyclinic.com/ on my MY04 that has PPP fitted, Is this a good idea ? It looks like a straight forward fit is there anything else that would needed to be done once it is fitted ?

cheers Tim

No power gain at all, spoils the smooth running of the car and could potentially cause damage. Your choice mate, but I would spend the money on something which actually gave a benefit such as handling products.

Go for an HKS racing type 2 valve. Ideal for high bhp/boost motors. Fitted mine to my jdm 94 wrx last week and sounds mint with a high pitch whistle.
