Tecnigas Exhaust Silent Pro (139QMB)

Tecnigas Exhaust Silent Pro (139QMB)

Description: Tecnigas Exhaust Silent Pro for 139QMB 49/50cc 4-stroke engines. The Tecnigas Silent Pro exhaust improves torque over the stock exhaust, all while being quiet and maintaining a subtle look. Works well on retro style scooters with lower body panels.

When changing a cylinder kit or an exhaust, it's a good idea to pick up a few extra exhaust studs + nuts M6 set since these can easily need replacing and bring your project to a grinding halt while you wait.

•    Head Pipe Bolt Hole Spacing: 50mm
•    Head Pipe ID: 18.5mm
•    Fit Exhaust Gasket: 27mm / Studs: M6 / Nuts: M6 / Socket: 10mm
•    Fit QMB 49/50cc+
