Any part of the underbody which was painted, was completely fine though.
That being said, maybe it's just how all cars are now.

Dude. It is an exhaust. They rust. They always have this is not new. I had 80s cars where the pipes were rusted through and falling off in only 5 years so even ours are a wonder product in my eyes. They rust the same on every car unless you spend the mega bucks for full stainless or some of the high end alloys.
Heat + moisture = RUST.
