Giannelli G-4 2.0 for Vespa GTS 300/300 HPE

Giannelli’s new Vespa GTS 300 2017 on and GTS 300 HPE 2019 on exhaust system is now available from VE (UK), perfect for owners wishing to either replace their standard exhaust due to failure or as a performance upgrade.

Giannelli’s “G-4 2.0” exhaust system features a brushed stainless steel silencer and header pipe and has been designed to offer performance increases across the rev range while remaining road legal, as well as a weight saving of up to 3kg when compared to the original exhaust.

Key upgraded features from the original G4 include integrated bracket, sleeker look, and shorter link pipe to allow the use of the original exhaust elbow and removing the need for the link pipe to silencer gasket, saving time and problems with seized exhaust studs and lambda probe.
