Right fitted mine today and I have to say I am a bit disappointed. I love the look, engine bay looks much better with the engine cover removed and the product is good quality however I am not overly keen on the noise it makes.
I was hoping it was going to be quiet from what I've read however you can hear it sucking air from the glove box area and when you release the throttle it makes a kind of whoosh disssh similar to a dump valve sound but not as loud.
They all do this, its not really something that can be avoided with induction kits. if its any conciliation, Id be shocked if it ws as loud as an ITG or Evoms.
It's not as loud as ITG or twintake, I heard them both on GTI's and Edition 30's before I opted for Volant.
If you have an aftermarket exhaust you wont hear it, if its std exhaust you will notice it for while until you get used to it
