I used to work in a muffler shop so I know about the thin pipe trick. We never used it. We used the heavy pipe and good mufflers. The cost is about $10 or $20 per car more - our customers didn't mind, their exhaust systems lasted 2 or 3 times as long. If you really want them to last, paint the pipes and muffler with 2 coats of hi temp paint before installing and you will double the life again. I use brush on silver stove pipe paint from the hardware store. On my pickup truck the pipes looked like new with no rust after 8 years. Then I sold it.

So I'm looking at a life of about 10 years for the cheap setup the way I do it. I really don't expect a 20 year old car with 322,000 KM on it to last longer than that.
