Piaggio 8263885 Graphite Bush Exhaust Gasket – Vespa GTS, Beverly, MP3, Medley, Aprilia, Gilera

The Piaggio 8263885 is the graphite bushing that creates a seal between the manifold and the muffler; it is an original Piaggio spare part. It is the ring that gets compressed in the joint to seal the exhaust: when it crumbles or dries out, you get that classic puffing sound upon acceleration, the smell of gas under the seat, and sometimes the check engine light comes on because the oxygen sensor is detecting false air. It costs only a few euros and must be changed every time the muffler is removed – it is effectively single-use. This is one of the most widely used part numbers in the group: Piaggio, Vespa, Aprilia, and Gilera, from 2005 to the models on sale today.

Compatibility

Who is this perfect for?

This is the spare part for those who hear a sharp puffing sound when opening the throttle, or smell exhaust fumes rising from under the seat. These are the symptoms of a worn graphite bushing: the joint between the manifold and the muffler is no longer sealed. It is also an essential part for any exhaust work – replacing the muffler, the catalytic converter, or removing it to access the engine: the old bushing cannot be reused. It costs just a few euros and makes the difference between a job done well and one that needs to be redone.
