After reading many debates on forums about Aftermarket dump valves i decided to bite the bullet and i fitted the HKS Super Sequential Blow Off Valve onto my Hawk-eye.......must admit sounds and works great on car, decided against induction kit and fitted cosworth panel filter instead, any other guys have different set up??

Yeah the HKS Dumpvalves are nice, I used to have one on my Old soarer.

Is it "Bailey" that make the chattering dumpvalves?

I have a forge one on my hawk eye and it's very loud but does sound and work well. Not done a filter yet but will change soon ;)

I was right.. Bailey Dump valves

Just for reference

I've got the same on mine HKS SSQV and panel filter but decided to have a change and have now changed the fin in the DV just to be different - sounds great not too loud unless you are giving it some ! ;)

yep noticed the difference in sound when booting it....brings a :) everytime

i have a baileys dv on my 96 wrx its not very loud but does give off a nice chatter i might look into a hks or forge myself by reading this. :)

HKS does the best sound IMO I want to get one but I have the baileys one on, so it's down my list :)

Vent-to-atmosphere dumvalves pay havoc with Subaru's twin-turbo system so standard all the way for me.  I do have an STi panel filter though.

I have a Baileys dv on mine but with my car being automatic i tend to loose a bit of power when its dumped. I'm not sure why any ideas???

 Yes they did :D i've heard they are rare

I changed from panel filter to induction kit Not seen any improvement really but looks good ;)

Hi all i have a HKS and panel filter on my 2000 WRX. THE valve noise changes dramatically depending on wether or not your giving it some spaghetti !!!!! Loud and proud :D

I have just fitted a Bailey to my leggy and I believe its a chattering one, will find out when I take it out tomorrow lol.

oooossssshhhhh!

Utterly....flutterly......oooossssssshhhh..!!

Hks best sound when you stamp on the loud peddle up to 5krpm then back off, whoooosh, std filter but thinking about a blitz sus induction kit.

I have to agree I'm toying with swapping over to the HKS seems to have a nice flutter to it.

Mine already has a Baileys one fitted (exactly the same as the top middle of the pic originally posted), and tbf it sounds really good, not stupidly loud unless you obviously give it some beans ha ha. Although I might go on Youtube and have a listen to the HKS one everyone seems to be raving about :)

Think Ill be keeping mine as a recirc but changing to the forge item - shiny shiny

mines been mapped with it on and I must admit I do like the swooosshh when I change gear :D I'm like a big kid what can I say :)

Mine came with the bailey one fitted. Sounds ok and will do me til i have the cash to consider replacing it.

 

I've removed the sound deadening from the underside of the bonnet and that has actually made a difference..... its much louder when dumping at full boost :D

 

i am a big kid i know lol.

I miss the sucking and whooshing of an induction kit and DV :( it,s about £700 new for both bits and a remap, far too much for some extra noise. Whish I'd kept the HKS SSQV from the classic would have only needed the fitting kit then :(

Hmmmmm HKS SSQV :)
