Just been having a look at dump valves for the vRS and come across this.

Stealth Dump Valve

Thought it might be ofinterest to you. Bit pricy at

I'm no expert on DVs but surely this BOV is unsuitable for the 1.8T since it vents to atmosphere unlike the standard one?

I believe KarlRS has one of these fiited. Dave (DaveU) has one in his passenger side footwell ( ).

It does work and the idea is that you can "tune" the amount of venting sound. I know though that it's larger than the standard DV and you either have to cut the engine cover and play around with the pipe work. I think it part vents in the airbox and part atmosphere....someone will know for sure.

I think Dave's going to fit his soon although the induction kit he has make more than enough noise.

I suppose it depends on what you want; if you want noise then get either this or a Forge. If you want something more repliable than standard then get a Bailey. I found it to improve response and it costs only
