You have a Re circ valve, but in order to vent into the atmosphere, you would need a MAP system since the air the passes thru it has already been counted. You would also need a unit with a stiffer spring.
I have a SS J Pipe and my Re Circ valve DOES vent back into it, but in order to make her fit, I have to use a 90 degree elbow. When it vents back.... I can hear it as loud as hell from inside the car. It makes that 6 million dollar man sound too

I heard the Forge valve today on John (I think jvd951's) 951 at the autox...
It vents back to the intake and sounds Very sweet...his car has a Autothority MAF, 3" downpipe back exhaust, 1 of the 2 intercooler pipes upgraded...and a host of other mods...16psi boost.

you mean, turbo to IC? that's odd. becuase the IC is only 2.25 in'. and the IC to TB pipe has that large kink in it. I bet they flow about the same. <img src="confused.gif" border="0">

Just to let you know, the forge is NOT audible from inside the car with stock air box, AFM, and intake tubes. With a MAF or a MAP conversion it becomes audible.

Maybe.. At the time I wasn't sure which BOV I wanted, and couldn’t justify the prices, so I decided to replace just the one pipe until the OEM BOV failed. With the stock air box out of the way, the turbo to IC pipe can be made one straight piece. Much less restrictive in my mind.
944T - If you’re looking for loud go with the GODZILLA with Discharge Horn (will require new IC pipes$$$$) <a href="http://www.turboneticsinc.com/catalog/bypass.html" target="_blank">http://www.turboneticsinc.com/catalog/bypass.html</a>
If you’re looking for affordable and functional quality the Forge unit is my choice.
