Spray-on foam, soot and corroded metal
I've been borrowing Dad's huge Citroen Synergie. I've had a few problems with it, but none as bad as yesterday's...
...the exhaust pipe, which I now realise to be as old as the car has literally rotted and turned to brown dust. Here's a picture. Nasty, isn't it? The problem point is after the cat and just at the join to the small box.
The car sounds like a tractor - I literally have to coast past pedestrians to avoid attracting attention (this car doesn't normally turn heads). In addition, the fumes are coming out under the car and getting into the cabin, which is unhealthy and unpleasant. Interestingly, the performance has improved dramatically, effectively making the engine note and road behaviour like that of a hypothetical "sports tank". I assume the improvement in acceleration and extra torque is due to the car not having too much difficulty in expelling the exhaust gas.
Well, I'm obviously not driving it any more as running without any exhaust compression could damage the engine, according to Dad, but on a bank holiday weekend, I can't get anyone to mend it, either. And no temporary fix will work as the metal is so fragile.
Here's the musing:
What about some thick, spray-on, heat-proof foam? If no part were available, you would simply align the two broken components, support them temporarily and spray the gloop around the join. It would expand and set hard, fixing the pipe in place.
Anyhow, muse over. I'll have to get it fixed on Tuesday, but I might be able to order the part before then.

Does this look right to you?
