When I was a kid growing up on the farm, we would have to go out and check the irrigation system at least once during the night to make sure that it was operating as we hoped it would. The pump engine's exhaust manifolds would glow with a dark red color all night. Most of the time a person doesn't think about that when driving a car during the hot times of the year but that old manifold takes a beating from the heat. The weight of the exhaust system certainly doesn't help but it takes quite a few long miles to get them to sag. If they could talk, they would be screaming for mercy and be telling us traumatic tales of woe.
