I don't like wrap, it might work but looks poo, looks like you're trying to cover up bad welding. LOL. I say a nice heatshield with asbestos on the one side of it, towards the hot thing.
ceramic coatings - I don't trust it anywhere inside anything, I only do mild steel steel manifolds on the outside to make it look - Bling. Helps with the rust as I can't find paint that lasts on a turbo manifold. Ok, it helps with the heat too.
Heat wrap on my beautiful stainless tubes does the job. The aluminium shield that completely covered the stainless manifold did not help at all. I can touch the heat wrap after coming home from a trip on the highway while the car still idling to cool down. No more melted breather pipes!!! The quality of the wrap is important. The wrap I got from Rezlo is crap (sorry Ian) but the wrap I bought from XXX Sound in Centurion is da bomb, 15m per roll or @ R450 or R30 / m. I used about 10 meters. Keeping the rest in case I need to fix it.

I got about 14m of the stuff left, if any one want let me know, you can buy meter sections if you want.
Got no choice will need to shield, but now I'm only going to cover the essentials.
Mine is also very tight. This time I was clever... Put it on while the manifold was off the car. Always started at the engine side of the tube ending up somewhere on the turbo housing. Used hose clamps on the start section to secure, out of sight. The already difficult manifold is now even more difficult to mount because there is even less space between the tubes to tighten the nuts
