BOV/ Dump valve thingy

[dave2u]

I was down my local high street the other day and a sierra cosworth roared passed. The idiot must have hit 60mph posing. However as he changed gear there was the most awesome air release sound that was so dramatic i`ve decided i`ve got to have it.
It was i have come to learn a Blow off valve/Dump valve.
What ones do you have fitted on your SX`s and what are your findings. The noisier the better really.
And any stories of scaring the living sh*t out of cyclists so they drive into walls etc are also welcome.
As are free mods
er..and any money u dont need
er..and (men in white coats drag dave off and slap his straight jacket back on)

HKS Super Sequential Blow Off Valve is pretty popular. Check Blitz, HKS, (Apex too, I think)... they're pretty popular.

Yeah the HKS Super sequential is one of the ones i`m looking at yeah has anyone got one fitted? How loud is it?
Are they easy to fit?

I have heard some crazy ass sound clips of BOVs thye sound so nice. I can't wait till I get an SR then a BOV then I will liek never leave my car. Too bad this won't  be another year iunless someone wants to be VERY VERY generous and give me 8gs

uuuggghg I can't stand the sound of that thing.  I bought one for my onevia and that thing annoyed the hell out of me with that high pitch sound.  I like some of the other ones like the trust type s or r or even the blitz super sound but anyway I took my BOV and pulled it out of my car.  I liked the way the turbo sounded without the bov so I did the same with my new silvia.
