With the filter on, you have to listen for it. It's a soft, fluttering sound. Actually, never considered removing it. I like mine stealthy.

I replaced the ProCharger anti-surge with a Vortech Race valve, the sound is a head-turner!

I welded a 1.5" pipe (shown) to the flange included on the Vortech Race Valve. Also, the Vortech unit does not have the fluttering sound that I found to be annoying.

Very cool, good luck with your APS kit!!! I've noticed the Bosch BOVs included with the kit emits a nice subtle sound, if your looking for more sound, venting to the atmosphere maybe an option...since I run a speed density tune (mafless), I may go this route in the future.

Another option would be to replace the Bosch units with a direct replacement piece like the Hyperboost unit:

Jeremy,
For the s/c application, the Vortech Race or the Tial unit is suggested. The Hyperboost sounds nice on a turbo car, my buddy uses it on his Audi TT.

Brian at ICS Performance currently uses a HKS SSQV on his ProCharged C5Z, sounds wicked.
