Their BOV is set to vent atmospherically. This is the case with most aftermarket BOVs. If you know how to adjust them you can set it to vent back into the system. Most manufacturers like BMW, Subaru, Mitsubishi have their BOVs set to vent into the system. That's why you don't hear it from the 335, STi and the Evo. Hope I didn't insult anyone's intelligence.
