Tecnigas silent-pro exhaust system for Chinese GY6 50cc Euro1/2/3/4 scooters.

This exhaust is also suitable for Classic/Tommy low body style scooters where a low exhaust is required to clear the fairing/ side panels.

A quiet exhaust, especially suitable for original cylinders but offering significantly more power in the middle and upper rpms. Supplied in a black heat proof paint with a black heat shield.

Includes lambda sensor connection for Euro4 engines. Also included is a plug for the sensor connection so these can also be used for pre-Euro4 engines (Euro1/2/3).

These are not suitable for Euro4 Peugeot (Sym based) engines.

Engine mount type shown in image 2.
