The Danger Hot is only a sticker or transfer and should come off fairly easily.
Melvyn Rutter does a polished stainless steel heat shield which fits over the existing but is slightly smaller and therefore requires some trimming of the plastic.
I have one but my only criticism is that the polished stainless has a slightly different hue to the polished alloy of the engine.
The awful plastic original shields are painted by the Factory prior to fitting.
