Standard exhaust for GY6 125/150cc engines. There are different exhaust systems for these engines. The main differences are in the attachment of the system. The system listed here is attached to the rear swingarm in addition to the attachment to the engine case. Please see detail photos for exhaust mounting.
Exhaust system for scooters without secondary air system. However, the system can also be used for vehicles with secondary air system (SLS). For this purpose, the air connection with hose is placed in the fairing and simply closed. The power delivery is then slightly better than with SLS.
An exhaust manifold gasket is not included and must be ordered separately.
