Until recently, I had an '89 Celica. It got very good FE and was a great car, but its only design flaw was the muffler: the muffler would be shot in two years on average. (I had a lifetime warranty on a replacement muffler and must have hung at least six mufflers on that car over the years.)
One day I was cruising down a highway at about 65. The (then current) muffler had been getting progressively louder, but I didn't worry, because at worst, it typically would rust out and break off right where the pipe entered the muffler. This time however, I heard a loud BANG! from the rear. I looked in the rear view mirror to see pieces of muffler flying off behind me.
Yep, it exploded. Now you know what can happen from having a partially clogged exhaust. Purposely restricting the exhaust? No, thanks...
