Im probably gona get flamed for this but been "thinking" about fitting a dump valve. There seems to be loadsa different types and they all vary in sound and loudness. Im not looking for the 'hiss' or 'pshhh' noise but the ones that make a 'whistling' noise. Like a 'high pitched hiss that whistles'. LOL, Its hard to describe.

If anyone knows what Im on about, let us know which Dump Valves make this sound.

>Gets ready for flame posts...

Cheers.

Aha, thanks subaruturbo, just looked up the HKS SSQV on youtube for a sound demo. Thats what Im looking for, are there any others similar to the HKS one that anyone can recommend?
