How to get 37 more hip out of an engine without touching the engine?

To get the VQ engine to produce more power without changing any of its award-winning fundamentals, Infiniti engineers simply recalibrated how air goes in and exhaust goes out with a variable capacity muffler. In the first figure, when pressure inside the main muffler is low (at idle or constant speed), the control valve is closed. In the second figure, when pressure inside the main muffler is high (during acceleration), the control valve is opened. Reducing the exhaust system back pressure helps maintain a consistent, progressive torque curve.
