I recall the old mild steel, or whatever mufflers were made of back then. Rust out within about 5 years. But for about 30 odd years now our vehicles have been stainless steel and I think maybe the reason for that upgrade, might have something to do with emission laws, but not sure, just a guess.
But we have had 5 new vehicles (all GM) since 1989 and nary a muffler or exhaust replacement. We had the big Buick sedan for 13 years, nada. Boy I miss that big 6 passenger Buick sedan, Regret trading it in. What a car, Powerful, tremendously comfortable, quiet as a mausoleum .
