2012 Camry: Eyesore under the hood

Recently looked at some 2012 Camrys at a local Toyota dealer and was somewhat shocked to see that none of the power plants had an exhaust manifold shield/cover. While the average Joe/Jane probably wouldn't notice anything amiss, this was the first thing I noticed after popping the hood.

The salesman claimed that they rattled over time so Toyota had stopped using them. A head mechanic said that they did have covers originally but the upstream O2 sensors had to be replaced with longer ones and so the covers could no longer fit.
