Like title says fitted new dv and its as quiet as OEM one. My mates one dumps really loud but he is running a evoms air filter. Now should mine be noisy or become noisy with air filter? Or is mine a dud. It feels like its doing its job as mine was shagged. Your views pls thanks

which valve do you have fitted?

I recently had the forge atmospheric valve on my VRS and it was rather loud, then I put a Neuspeed p-flow induction kit on and my valve was ridiculously loud. Thats why I had to remove it :(

Same as urs but just no noise. Will have a look and see what spring is in it if that makes a difference. What colour is it for standard set up black?
