Ceramic coating exhaust manifold - worth it

[Mightymetro]

With the refurb consisting of lots of new parts and blasted blocks etc the exhaust manifolds on my v8 are oooking a little worse for wear.  Just wondered if anyone had any opinion or advice on ceramic coating.  From what I can gather it looks better and helps take heat from the engine, however I worry that the extra heat will just be transferred to the turbos that are not intercooler in anyway so it’s ying and yang?

Wouldn't it be better having a stainless steel one made up.

I think the price for a set of stainless headers for a v8 is over £1500 🙈

I used Zircotec for a number of exhaust manifolds on V8 projects.  It's good stuff and not hugely expensive.

I've recently had a quote back from Zircotec, manifolds and hot side of the turbos as per Mikes first photo above, £630+vat.

Yes expensive, but we'll worth it IMO, not only to reduce engine bay temps and heatsoak in such a confined space, but also improves exhaust gas flow, and if extended to the hot side of the turbos promotes faster spool up, reduced intake temperatures and performance gains associated, you could call it a ceramic chargecooler.

Thanks for the replies.  Unfortunately I can’t do the hot side of the turbos now as they are marked up,after the rebuild and can’t be split back down as it voids the warrenty.  Choices choices.
