If using high temp paint is it worth it to try and keep the temp contained within the exhaust manifold/shstem without having to use a wrap, which I'm lead to believe can bring on premature cracking around welds.

If paint is the way to go and the manifold is not brand new, should it be treated to one of the many rust inhibitor gels on the market after cleaning, but before high temp paint is applied?

not worth it not found one that does not burn off. and the paint does not contain the heat. wrapping just shifts the heat under the car which can result in burn paint in the tunnel.

How about ceramic coating, lasts better than paint and keeps the heat in.

only give about a 30% reduction and you burn paint off further down the car.

Probably keeps the intake charge cooler though. I'll suffer a little burnt paint in the tunnel for a couple of HP.

You’re not likely to see any power increase that isn’t a rounding error. The only reason to pursue it is if you’re struggling with under bonnet temperatures.

If you haven’t already, you’re better spending your money on an improved cylinder head, cam and a RR session.

a couple of BHP. no way. a fraction may be. but like i have said yet to find one that lasts any length of time.

I think the combination of lower intake temperature and higher speed exhaust could feasibly give a 2% increase in HP.

not an expert, but I think if it would do that then everyone would know about it by now. There must be quite a few people that have tried it before

The boys on the evo forum did back to back results, will see if I can dig out the link.

Ceramic coating is worth it mainly for engine bay temps and turbo applications in my opinion. The key to its application is in the prep work by the company applying it. I had a turbo manifold done on my old evo 9 and it was rock solid for the 2 years of hell I put it through.
