Full exhaust system GIANNELLI G4.0 with CATALITIC EURO5 HOMOLOGATED manifold and muffler silencer STAINLESS STEEL HOMOLOGATED EURO5 for PEUGEOT METROPOLIS 400 17 -- 21

G4.0
Giannelli introduces a new range of exhaust systems for maxiscooters: from G4 2.0 to G4.0.
This new proposal for Maxiscooters for Giannelli keeps all the great, peculiar G4 2.0 features (performance, reliability, lightness) with some essential improvements, coupled to some important changes in the look of the silencer, like the heat cover, black finish rear endcap and a new, nice “G4” logo.
G4.0 exhausts are available for a wide range of maxiscooters, Euro4 and Euro5, being constantly updated.
