Not every turbo car has it. For example neither yours nor mine has it. To get the loudest possible sound you'd need to vent at least some of the air to atmosphere, but again, it's metered air, and in my view the tradeoff is simply not worth the hassle. You can consider what's called a snorklectomy, where you would remove a ~1L plastic "box" in the fender (look on the driver's side of the car where the intake tube goes from flat to rounder and enters the fender; on the other side of the fender there might be a box as I've described depending on the particulars of your model). Search for snorkelectomy or snorkel removal or delete etc. here for more info -- but reverse any "sided" directions because it's likely the author sat on the left side of the car to drive, whereas you do not.
This will make your intake noises a bit louder and you may hear the stock valve from inside the car. It should not affect metering at all so it'll maintain good manners when the car is running, when you shift, etc. Be aware of how water might affect the car with any changes you make, and strive to keep everything reversible should you change your mind, sell, etc.
