I can feel mine opening, and you can probably feel yours too. At full throttle they open at about 3200 RPM IIRC, and otherwise at about 4000 RPM. If you accelerate with just enough throttle to slightly gain speed just under 4000 RPM you will feel the power come in as they open. It will not be earth shattering, but it will feel as though you increased the throttle even though you held it steady.
