Put a baileys on my wrx 2 months ago only because its the first scooby ive had and love the sound but ive now been told it could effect your bhp and running to rich, its my pride and joy and if its going to cause harm its off...any advice?

No dump valve.

This is locally called a BOV. There is a million-page thread on this subject here:
"The BIG BOV thread" (Where all bov question threads get merged)

It's a very long and informative thread. Here is my summary:
No.

Great, welcome. In my signature there is a link and if you follow that there are other links with info on every system in the car. The terminology is localized but you'll be able to follow along no problem, and I think you might find it interesting. Hours of fun reading. Enjoy the site.
