I just installed my brand new HKS SSQV.  It came pre-welded to a hardpipe that I just bolted in.  I also got the Recirculation fitting.  After I ghetto-rigged a 1 in spa flex hose from the bov back to the intake, I went out for a test drive.  Letting off during boost, even full boost(stock), it doesn't make any sound.  I've read that this is supposed to be very loud, but I can't hear anything.  I know that with the recirculation, it would quiet it a little, but I wouldn't expect nothing.  Any help would be appreciated.  Thanks
