GY6 50cc (139QMB) Minarelli Exhaust Hardware Kit 6mm 8mm

Exhaust Hardware Set for GY6 50cc and Minarelli Engines

This exhaust hardware set suits GY6 50cc and Minarelli engines and includes what you need to fasten your exhaust system securely. It has a metal exhaust gasket, stainless steel studs, and steel cap nuts that together help create a tight seal and keep exhaust from leaking. It is one of the GY6 50cc scooter parts that help keep the exhaust connection sound.

What's in the Box

The set contains one embossed metal exhaust gasket with 49mm bolt hole spacing. You also get two stainless steel exhaust studs, offered in M6x1.00 or M8x1.25, and two steel exhaust cap nuts. Together these parts cover a full exhaust flange service.

Fitting and Swapping Out Parts

Keeping exhaust hardware in good condition matters for engine running. With time, wear can open up exhaust leaks, which can cut down on efficiency. If your exhaust system is giving trouble, check the gasket and studs and replace them if needed, particularly when you hear unusual noises or notice a drop in performance.
