Is the exhaust sound adjustable with a valve?

[LaLena]

Valve exhaust sound is adjustable. The valve exhaust can alter the sound, as the exhaust note differs when the valve is open versus closed. Many supercars come equipped with valve exhaust systems from the factory. The exhaust sound varies when switching between sport mode and normal mode, which is the function of the valve exhaust. Properly installed exhaust valves not only control the vehicle's exhaust sound but also more effectively manage exhaust backpressure, keeping the vehicle in optimal condition. If the exhaust valve's opening and closing timing is inaccurate, it can be highly detrimental to the engine's power output, especially at high speeds where smooth exhaust flow is crucial, leading to significant negative effects.
