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

Well I can only speak from experience.
I fitted a Turbo XS VTA dump valve to my STI 4 (MY1998). I was 24 at the time and just loved the noise it made. But there was one issue....the driveability.
On part throttle, the motor was very jerky, so much so that I thought I had a problem.
I changed the valve back to standard and the problem went away immediately.
I also noticed that there was less lag when I changed gear with the standard valve as opposed to the vta. I believe many vta suppliers quote a different story!
I also noticed the same when a friend of mine bought another of my old scoobies and fitted a HKS vta. Yes, it sounded great (at the time - grown up a bit now!) but the 'stutter stutter judder' symptons were still there.
For £200, I'd spend it on ****** and coke!
