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

The Piaggio 8263885 is the graphite bush that seals the connection between the manifold and the muffler, an original Piaggio spare part. It's the ring that compresses in the joint and seals the exhaust: when it crumbles or dries out, you get the classic hissing sound on acceleration, the smell of gas under the seat, and sometimes the engine light comes on because the oxygen sensor reads false air. It costs only a few euros and should be replaced every time the muffler is removed – it is essentially single-use. It is one of the most widely compatible parts in the group: Piaggio, Vespa, Aprilia, and Gilera, from 2005 to models sold today.

Compatibility

Recommended products

• Exhaust clamp and studs – they get damaged along with the bush, especially on vehicles that have been exposed to salt
• Manifold gasket at the cylinder head – the other sealing point of the exhaust
• High-temperature exhaust sealant paste – useful if the seat is slightly worn

Who it's perfect for

This is the spare part for those who hear a dry hiss when opening the throttle, or the smell of exhaust gas rising from under the seat. These are symptoms of a worn graphite bush: the joint between the manifold and the muffler no longer seals. It is also the essential part for any exhaust work – muffler replacement, catalytic converter replacement, disassembly to access the engine: the old bush cannot be reinstalled. It costs only a few euros and makes the difference between a job done well and one that needs to be redone.
