I have a customer of mine that wants me to make his ST chatter( u no the noise that you get when you have no dump valve and the excess boost is released out the air filter) He has induction kit to be fitted to it but I was just wondering if anyone had done this before? I'd imagine all you have to do if find the standard Ford dump valve and render it usless? I will probably be able to sus it out when I have the car in front of me but I was seeing if anyone could give me an idea of what the job is like?

Cheers lads
