The new Euro 4 & Euro 5 Vespa GTS exhausts have changed and fitting an aftermarket exhaust now only requires a ‘slip-on’ can, rather than the full system.
Here’s the latest one from UK based manufacturer, Scorpion Exhausts. It comes with a lifetime warranty, boosts power slightly, comes in 2 stainless finishes (no rust) and sounds good. You can buy one direct from ScooterLab.UK or your local Scorpion dealer.
