Inner muffler Jamarcol exhausts for Vespa/Piaggo 4-stroke – 2V / 4V models

Do you (mother) think your scooter makes too much noise since you installed that fancy new Akrapovič look-alike exhaust from Jamarcol? Or would you rather not stand out too much because your Vespa scooter is faster than Max Verstappen?

Then buy this inner muffler, possibly in combination with the dB Killer. Brings the noise level to an unobtrusive value without greatly affecting performance.
