How much louder are these BPV's going to be relative to the stock ones? Anyone that has them, do you have them dump into the atmosphere or do you use the stock configuration? Anyone know of an online store to purchase?

If you can hear you BPVs then something is up! My old faulty stock ones sounded like BOVs!! My Forges (with high temp mobil 1 lubricant) are very quiet and you have to try very hard to hear them.

so i should not hear any "woosh" sound when i let off throttle? What is the difference between a blow off valve, and a wastegate/by pass valve? I want to have a slight "woosh" sound, but not to "ricer aggressive".

After installing my Forge valves, I started to notice a whoosh kind of sound as I let off on the throttle at high RPM's. I had to be going a low enough speed to hear it though, with my windows down. I kind of like it.
