New exhaust system rubber has come out on hangers

Looks like the rubber only has raised edges on one side vs both so it stays put in the metal bracket? Anyway, Maybe those style clamps work for factory systems but I’ve had a few cars with muffler shop work either already done when the car was bought or had work done ourselves and have had the hanger rods break.The design is for speed of assembly vs longevity like the old style clamp hangers, which take more time to affix. But they work and they last.
