Yesterday, my Vespa S 50 2T got very loud, and after a few stops, I observed that a small pipe coming from the engine right to the exhaust got disconnected.
Now the engine is very loud, and the sound is coming from under the seat.
The connector looks like a blown-up diy garden hose. Do you know how the original connector/part is named?
LE:
After many searches, I found it: Connecting Rubber PIAGGIO secondary air tube, exhaust, 827443
Now my Vespa doesn't sound like a Harley anymore 🥲
