I am a vendor but i'm also an enthusiast just like you guys.

They are essential for me because they offer the flexibility to adjust the sound volume as desired. Whether you prefer a significantly loud exhaust or need to keep it quiet while approaching your neighborhood or workplace, valves allow for such control.

With a valve controller featuring multiple settings, you can achieve an intermediate level between fully open and fully closed. It's not unreasonable to want to retain the original features of the car, especially when considering installing downpipes that could significantly increase the volume.
