Vespa GT/GTS/GTV OEM Exhaust Gasket Bushing

Seal your exhaust system properly and eliminate annoying leaks with this Genuine Piaggio OEM Exhaust Gasket Bushing (MPN: 8263885). This heavy-duty, high-temperature graphite/metal composite bushing fits directly between the exhaust header pipe and the main muffler assembly, ensuring a completely airtight seal.

Because the exhaust system is subject to extreme thermal expansion, intense vibration, and corrosive exhaust gases, this bushing degrades and crushes over time. A worn-out exhaust gasket leads to loud exhaust leaks, deceleration popping, and loss of essential engine backpressure. To maintain optimal performance, it is highly recommended to replace this bushing whenever you remove your muffler for rear tire changes or suspension service.
