This way of thinking will cost you a lot of money. I did so on a previous car and now thinking, it was not worth that money, not to mention time.
At this age, I would carefully inspect most components, such as suspension, pulleys, exhaust, springs, fuel/brake/steering lines -as you did with the pictures. If anything seems deeply rusted I would replace it. If it only has surface rust, I won't touch it but try to cover it with some rust protector. I did so on the power steering lines which are prone to rust and sometimes will start leaking. But if it's only surface rust, some rust protection will help these last another 5 years. That bulk after the catalyser may be a previous welding. Scratch the rust and see if there are layers of rust coming off. It so, it's better to bring it to a muffler shop, it might save a surprise one day while traveling or having a busy schedule.
A thorough inspection is the best thing. Last week I heard my exhaust pipe growling and this week I had a look and the two bolts that were connecting the catalyser to the first muffler almost felt into my hand. This is the kind of thing that can be detected on a preventive inspection.
