exhaust system LeoVince 4T Racing HM-Titan for 139QMB/QMA

Leovince`s 4-stroke exhaust system features a motocross-style silencer with a coarse but not too loud 4-stroke sound. The exhaust, as usual is very well made and mounting hardware is included along with a set of yellow clutch springs. The silencer was borrowed from the LeoVince Exhaust Pitbike, and thus delivers optimum sound performance. Probably one of the best exhausts for the 139QMA/B engines on the market. Only for scooters with single rear-shock
