As said in the other thread mate that look sweet As for the chattering dump valve, its not a dump valve The noise is caused by blocking the standard BOV up so the boost pressure goes back into the turbo and gets chopped up by the turbo hence the chattering noise. if you run the induction kit straight off the turbo then you will get this noise better but you would have boost creep and other issues so you would need other mods to get the best out of it I would get an adjustable BOV like a Greddy Type S and adjust it so it goes off on full boost so you still get the chattering noise when on less than half boost Hope this helps
