I need FP Manifold (w/ ceramic coating) users to chime in.
Is the coating worth it?
How big of a difference does it make.
Finally, how long does it last before flaking off?
 
I have two experiences with the FP manifold with ceramic coating from FP (who uses an outside company for coating).
First manifold I got from FP with ceramic coating was terrible as the company, who did the coating, only used one coat and it started to flake off after 100 miles or less. However, FP made it right and sent me a new manifold with coating and let me keep the other one.
The second manifold has held up great, however, it still puts off a lot of heat. Best thing I did was put a blanket on it. Before the blanket you could not get near the manifold after driving and with the blanket you can touch it after driving.
 
+1 on the blanket. You can find them on ebay. I think it was around 100 bucks; it's a company in Idaho that sells the one I bought. I can't remember their name but I stumbled upon them on ebay after I bought mine. @GST with PSI told me about this particular company.
 
Pardon my ignorance, but wouldn't a blanket keep the heat "in" whereas that is not something one should usually want, especially on a Turbo car? Just wondering..
If I understand this correctly, you want to keep the heat in for 2 reasons.

1. Keep under hood temps down
2. Allow the manifold to cool down slower after the car is shut off
 
I took the blanket off mine when my manifold cracked. I didn't like not being able to see that I had a huge exhaust leak. It was nice for keeping the under hood temps down before that, but I preferred the look without it anyway. I bought it to help with the temps, but upgrading my radiator and ducting the underside (I kept my AC when I added a front mount) took care of the issue more than the blanket. I know other people with the manifold and the blanket together with no issues, so I don't think that's what caused the cracking, but it did make it harder for me to figure out what was wrong. More than likely, it already had a hairline crack when I put the blanket on and it just got worse. I liked the manifold enough that I bought another one though. I'm debating having that one sent out for coating.

Worth noting that I got the manifold used and my issues came up after installing the fmic. I have no idea how hard it was used before I got it, so I'm not upset with FP or anything like that.

I'm actually replacing a cracked FP mani with a new one. I was hoping to prevent the new one from cracking in the future.

You do want to keep heat in pre-turbo. Hotter gases flow faster and have more energy to expand. This expansion and increased velocity allows more pressure to be exerted on your turbine blades, thus decreasing your turbo's spool time. Another benefit is lower under hood temperatures, which will decrease intake air temperature (especially for people running air filters exposed to the engine bay).

On the other hand, keeping all that heat in over time may prematurely crack your manifold. But I think the benefit of keeping everything under hood cooler is worth this risk.
 
I haven't ceramic coated an fp manifold yet. But I did ceramic coat my evo 3 manifold and use the stock heat shield It definitely helps out. As for how much a difference it makes I wouldn't day worlds difference but it does. I also had my manifold/turbine housing and o2 housing ceramic coated by Detective coating and still hasn't flaked off.

like he said ...the power to spin the turbine comes from the energy of expanding gases ...hotter the better and closer to heat source the better
