Doubtful you would even notice the difference. It's essentially a silencing tube, though you are changing the characteristics of the airflow. I consider it like a performance intake, the only real gain is in glorious sound. The EvoMS V-Flow intake on my 996 didn't change performance in any perceptible way, but the howl under throttle is worth every penny. My biggest complaint with the 986/996 is that in stock form, they are way too quiet. A few modifications make them sound like a proper Porsche.
