You will find that coatings will barely (if at all) reduce teps read from your sensors. They are designed to keep radiated heat down. If you put a thermometer say 2in from your manifold before and after coating you would notice the difference. My mate has just turboed his CRX and the exhaust manifold is HPC coated. You can put your hand mm's from the surface and although you can feel the heat it wont burn you like a cast manifold or an uncoated one will, however the split second you touch it it will rip your skin off 
It is designed to keep the heat in and reduce your underbonnet airfilter and pipe work is located it may help a little howeverdue to the surrounding air being cooler. By keping more heat in manifolds it can help the turbo to spool up slightly quicker as less heat is lost to the surrounding air.
