Which dump valve?
The original recirculating one is best for your car, but if you want a woosh then the turbosmart megasonic is your best friend. matty is selling one but you will need an adapter made for it to fit the top mount intercooler.

I used to have a Turbosmart dump valve, it was on the car when i bought it. All my mates said it sounded great, i found it ok but i put the standard dump valve back on because i hate dump valves personally
Not as chavvy as big spoilers and exhausts though which nearly every spotty teen has on their motor! Must be the area I live in but I've never seen a 12-17 year old rolling round in an Impreza

Unless you want overfuelling, with possible borewash, and your cats, if any, knackered, stick to the dumpvalve you have.
And don't touch Baileys with a ten metyre pole: cheap crap.

I love all the comments made against dump valves.
Dont listen to all these old farts

I have an original HKS ssqv on mine, for me,too quiet,chirpy,been on the car for 5 yrs now with no running issues so thats good,but currently have the megasonic to swap it out with (yes,im a 31 yr old chave but hey)
I spend too much time shouting at the kids so cant shout out the window when i`d like,hence the dump valve.
im not into sleepers,hence the d/v, hi level spoiler (which hold their value still for some reason (genuine ones )
)/mudflaps,you get the idea 
If you like them,run one,if you get fuelling issues,dont run one,when i went back to recirc my mpg was pretty much the same,maybe a couple of mpg`s more,but that could of been cause i had a slower driving week etc.
the pro`s/cons all vary,d/v`s help the turbo life by not casuing it to stall etc,but thats another thread,isnt it lads

Running no dump valve sounds even better!
You'll need a stronger turbo in the TD series and a fmic with induction kit to achieve the best noise
I love the sound my car makes, its what ppl refer to as turbo flutter... its actually the noise of the air going back thru the turbo in the opposite direction when off boost as the turbo stalls.
But the noise is brilliant!!!

I've got a TIAL which is a subtle low tish noise[not chav] and below .5 bar boost gives the lovely chatter from the turbo given the poundage of the spring in the valve.
oh and it looks

Don't fit one
Only the girls and chavs at Mcdonalds will think it's cool and you must be rich
The rest of the Subaru people will laugh at you
Also well documented on here about problems with them effecting performance and fueling
Do a search hundreds of posts on the subject over he last few years
Wooshh look at me
Duh
