Thermal wrap questions

So, I'm getting my exhaust done in a week. I wanted to wrap the downpipes with thermal wrap. Is there something you'd specifically recommend? Is some kind of wrap better than others? What can you tell me? I've got 2 downpipes, i'd say about 3 feet long. I found 2 kinds, but i'm not sure if the one is worth the price(about 200% of the other).
Thermo-Tec Exhaust Insulating Wrap this is the cheaper one
Thermo-Tec Series II Copper Exhaust Insulating Wrap this is the more expensive one.
Also I wanted to know if this Thermo-Tec Hi-Heat Coating is also worth getting.
