Greddy Type S works fine for me. As did the Turbo XS RFL.

I'm gonna run a Tial next..

 

Do not put a Greddy type s on your Subaru. Trust me, I also would stay away from turbo XS bov's for Subaru's. Like I sated before. If your on a stock turbo, or fairly stock set up (including a vf series turbo) stock is going to be your best bet. If you just have to have that bov sound, go for the tial or super sequential.
If you go front mount, and want recirc, go aps(I forgot about them in my first post). They have quality parts. Open atmosphere I still swear by the super sequential and the tial.

 

Greddy Type RS.

 

+1, ive had the blitz dual drive and now the type rs. the sound on the rs is way better and i've never had any problems holding pressure with it.

 

Subaru's are gay, they don't like Greddy valves. The WRX is like the gay red headed tree hugging step child of the car world. But, I did own one for 4 years, and I absolutely love the cars......The up side, you will learn ALOT about this car owning one.

 

you learn alot about any car you own for 4 year and if you dont then your a newb

 

his motor doesnt sound to healthy

 

You own a DSM, thats a learning experience in it self. If you still own one, you apparently didn't learn anything...jk.
I'm just trying to help the kid out. WRX's are picky about shit like that. It's one of those things you need to go with that will work well on that specific car, not how it looks/sounds/etc. They don't like to behave with certain blow off valves, simple as that. A little research about the car on nasioc, or any other subaru specific forum will tell you that.

 

neve rowned one this wasnt my usename in 04VW FTW

 

LOL good call. I was just messing with you anyway. Subaru's can be just as big of a headache as a dsm. But, Subaru guys love their cars, as do the hard core dsm guys. Whatever makes you happy.

OP, whats done to your wrx?
