Made for Maxiscooters!G-4 is the new exhaust system made for maxiscooters. Designed to be used on different engines (from 125cm3 up to 300cc and over) , G-4 exhasts are made with a collector and a silencer, both made in stainless steel, to replace the whole original system. depending on the application, a G4 system weights around 3.5kg and has interesting performance whilst being street legal, thanks to the dB-killer. G-4 exhausts are durable and reliable: materials, checks, processes and severe testing all contribute to make the G-4 a great system. Among G-4 features we can list a quick and easy fitment, by means of the mounting plate, the reduction of vibrations and shock, by means of silent-block bushings, the nice profile of the silencer, the surface finish and the laser-etched logo. Last but not least, G-4 exhausts are designed and made in Italy!
