My understanding (which could be wrong, so someone please correct me if I'm wrong) is that your car has 2 diverter valves (BOVs). A diverter valve can either vent to atmosphere or recirculate back into your intake; the 2 DVs in 996 turbos both recirculate.

From what I've read on here, you can run 1 that vents to atmosphere without getting CEL codes, but not both. Do a search for diverter valves on here to find more.

Also...wouldn't you rather save your money for a better mod? Save up for a tune (and shortly after, a new clutch) rather than the DVs imho...

Agency power makes one. Tight fit but gives you that pffff sound between shifts.

Yeah, I would forget about the sound that lets people hear the car is turbo, get a tune which lets them KNOW its a turbo.

If you're looking for more "turbo" sounds, an exhaust will give you what you're looking for. You can hear the "whrrr" of the turbos exhaust will give this to you.

Ah the sound of a bov and an exhaust pipe like a bumble bee with a tip big enough to stick your head in= annoying.

I use forge 008 bov but I diden t hear anything because I has the OEM airbox.

When I changed my setup to mAfless from Todd with air filters direct on the turbos without airbox ,the sound changed!

Search is your friend. For starters: Good tune, exhaust and diverter valves. Make sure the car is healthy: fresh plugs, 997 ignition coils, clean fluids (coolant, oil, brake fluid)
