I've had a broken flexi for a while but seems to be no leak. Before recent MOT, I tried putting a rag in the exhaust and it built up pressure OK. Couldn't hold it in. And my assistant couldn't detect a leak at the flexi. It passed MOT. Tester put a note saying that the front support was corroded. Meaning the flexi. So, I wonder what is the construction inside at that joint? Anyone know?
