the upper heat shield (the one attached to the converter on top) on my cat converter had become loose, and had been rattling for over 2 years. My tech advised me to remove it - said it would cause no harm, since there was another heat shield on top (about 4-5 inches away) anyway. Shall I just get it removed, or is there a replacement that comes that I can get installed (just the upper heat shield). Would it cause any heat damage without this shield?

Thanks a ton. The car is a 85 190E 2.3.
