there is no heat shield standard, i run the fibreglass type heat wrap and it seems to work o.k. one major problem (especially here in oz) is the termi system is so light, it's thin wall stainless, the heat radiates out something fierce! i've come back from a ride with small blisters on the back of my left thigh, and that's through jeans. also, mine is the "daytona 48mm" system and the only way to get the rear header pipe in was to unhook the swingarm from the hoop. a std sp5 system will just squeeze in but the spaghetti just won't go.
