NOTTE Slip On Exhaust for Vespa GTS & GTS Super 300 HPE

These audio samples demonstrate how this exhaust system sounds compared to the stock exhaust:

• EC Approved: This exhaust produces a fuller, deeper note than the stock system, with a noticeably more characterful sound as the revs climb.
• Racing: An aggressive sounding exhaust. Delivers a sharp, throaty roar with a pronounced crackle through the rev range - significantly louder and more performance-oriented than the stock system.
• Standard: The factory exhaust produces a quiet, muffled tone at idle that remains relatively subdued through the rev range - smooth and unobtrusive.
