hey Ive been looking around for a blow off valve for my 2010 wrxs. ive read up that putting a bov on can decrease performance as its not recirculating or something. anyone suggest a good blow off valve that works perfect for my model :) thanks robb

Myth that mate it doesn't decrease it nor will it give you any power gains either. It is meant to stop compressor stall on turbos help the life of the turbo but if it does or not I have no idea :D Some Scoobs don't get along with dump valves at all and a lot of people think they are very chavy. I have one on I don't care what people think to be fair I know 2 blokes in the late 50's that have them it's a personal preference thing really if your car will run with one on. 

But would look at the HKS or Baileys both do a good one just look out for lot's of fake kits too have a guide for the HKS on here what to look for and I will try get one up for the Greedy DV later. 

_{no performace benifit just a whoosing noise when coming off the gas.}

 

_{As Gambit the top one is the HKS but they nare rare 2nd hand and expensive new.}

 

_{DO NOT buy a cheap copy from Ebay.}

Heres the guide

what about a forge dump valve from a legit performance garage ? thanks. yeah I want the oosh noise I like it makes peoples head turn. flutter is chavy imo. but thanks again.

You see I like the futtery noise or the noise that is as close as it can get if you like to turbo chatter :D 

Forge is a good make too.

Just bought a forge dump valve fit it Saturday with new k and n drop in filter. Just need a nice cat back then remap. :)

All sounds good to me mate :D 

you decided yet on the exhaust ? 

Well milltek non res for 800 or can get invidia n1 single for 300ish but import.from rallysportdirect. Or the cobra exhaust about 350. Don't want ridiculous drone noise but I want to know I'm driving a subaru lol

Nice I'd have a look on You tube see if any of the video's have a subaru with the same exhausts least you will get an idea of the sound before you buy one I know most of them not that cheap to have to replace if you don't like it :( 

I had the same problem trying to find a dump/blow of valve for my car so many fakes yet so hard to find one to fit having the same trouble with lowering springs...

I bought mine from gorge itself hopefully it's not a knock off. :/
