You are only supposed to change the one nearest the airbox as i understand...
 
The one nearest the manifold is a Charge Relief Valve (CRV) and the other is the Blow Off Valve (BOV), you can safely change the BOV, but keep the CRV stock as i am lead to believe you will get pressure problems if you change both...

you just want 1 mate there is no point in having two, no one else ever has two, you will probably come into problems as the guy has said above

ive got a bailey venturi dump valve on mine, is very good, is not too loud but sounds good, not adjustable like some so easy and not so much to mess up, also looks good under the bonnet being nice and shinny

Just had a quick look on the net and the bailey one looks just what im after for my own \'7.  Dont suppose you know if yours is the DV36 or the DV34, just so I buy the right one!

Cheers :)

How much??? thats more than all the big jap brand ones. Plus i hear they are not that reliable or sound that nice. I quite like hks ssqv sounds good plus you can get a recirc kit for it.

well ive got one and im very happy with it, sounds really good and ive had it for a while now and never had any problems, is a very solid unit.  I had a greddy one before the bailey one and it was a load of crap and sounded rubbish.
