Can you hear your stock STi BOV?
I remember reading somewhere that people claim you can't hear your stock BOV on the STi. Well I just bought one from an older man who barely drove it ('04 with 3100 miles) and did not mod it, and I can definitly hear the BOV when I shift.
Like I said, the car is completely stock... is this the case for anyone else?

I've recently put the intake elbow in my 05 STi. Just now I can BEARLY hear any BOV. But just bearly and you have to listen for it... Was hoping for a little more noise when I put the elbow on...

You can hear the pfft but kinda muted. Wait till you remove the intake resonator or when you upgrade to a K&N Typhoon or some other short ram. You'll hear the whoosh noises even better |

are you serious? I thought that swoosh was a BOV... sounds identical.
Can you please explain the purpose of the bypass valve? I know in my honda I removed it (and I never heard a peep out of it). Thanks guys! |

Yeah, the by pass valve is definitely audible especially if your in 5th or 6th gear. Give it a little gas and then let go. It was fun for a few miles when I first got the car.
