Is this necessary for street/autocross/once-in-a-while drifting?? Am I overthinking it? I kinda wanna do both plus turbo blanket lol. But if it's a waste of money i'll just do one.
PS. I live in HOT Austin, TX.

Wraps > ceramic coatings
Don’t do both. The wrap will act as an abrasive that will wear away the ceramic coating. You could do a coating on the inside of the header only and wrap the outside, but there are two problems that could arise: one is the coating could chip or peal or whatever and get lodged in the turbo or catalytic converter; the other problem is having a professional make a quality weld if the header gets a crack. The coating should be removed before welding. Someone can make an ugly patch job, but the coating and soot would cause noxious vapor for the welder to breathe and cause porosities in the weld making it brittle. You could do a ceramic coating on the exhaust housing of the turbo then a loose turbo blanket, but the micro vibrations on a tight wrap would wear away the coating on a header, so just do a wrap.
If you have a stainless steel manifold then there is less concern of corrosion, but wraps can trap oil and water and moisture. Depending on where you live, wraps can a problem. The skid plate and other barriers will likely protect the wrap if humidity isn’t an issue.
For what it is worth, you could run the car hot then touch the wrap, and it won’t burn you. You won’t be able to do that with a coating. Last thing, some people have problems with too much heat being trapped by combining coatings and wraps or doing double wraps or overlapping the wrap too much.
