I've been looking searching around and I don't see the exact answer I'm looking for.

From what I read, exhaust wrap will cause premature corrosion on the exhaust systems.

Now, I have my exhaust manifold ceramic coated and I want to know if I put an exhaust wrap on it, will work together or the exhaust wrap will shorten the life of my manifold?

 

Now that the metal is covered by a ceramic coating and protected from the elements and moisture, I would think that corrosion would no longer be an issue.

I do not know about issues or problems caused by running both, though. Maybe someone else can chime in.

Have you checked temps with just the ceramic coating before you go ahead and wrap the exhaust? You might not even need it.

 

I haven't ran the temps.

I'm trying to reduce under the hood temp. as much as possible especially under dessert heat during autocross and track days.

After my 3rd run on Autocross last week, I popped the hood and it was so hot a had a hard time opening it. Just imagine the heat that the intake was breathing in.

If I can reduce the heat even more by wrapping my stock manifold with ceramic coat on it, that will be great.

As I was reading, the heat wrap keeps the heat but it causes too much fatigue on the manifold and it doesn't let it cool down that it shortens the life of the manifold. But it wasn't explained if it applies to aftermarket stainless steel or OEM cast iron manifold. I also can't find an answer whether it a applies even there was a ceramic coat on the manifold

 

Hmm not sure on that one but this is the coating I have on my manifold, maybe worth dropping them a email?

There seems to be an on going debate about this.. Some say adding the heat wrap is counterproductive to the ceramic coating.

Here's the link, it's from the suby forums. It's an interesting read.

NASIOC ~ ceramic coating.. plus heat wrap ?

I however have no first hand experience with this. I usually do one or the other.

 

I had both on my stock exhaust and noticed some rust on the corners by the bolts.. I removed the wrap and will never run it again

 

It'd be worth noting that the wrap can be abrasive if it isn't installed correctly. This can wear anything, including a ceramic coating down, and this could create issues.

Stainless steel shouldn't have any real corrosion issues, although sometimes with heat, and certain blends of metal on metal, strange things can happen (ask any good welder).

If you're realistically concerned about managing underhood temperatures, and getting a heat shield or ditching your manifold aren't options. Consider how you're operating the vehicle. If time allows, take it for a quick drive around the lot/area/whatever in a casual way to get some airflow running through. That alone will probably help dissipate those temps.

 

The debate has been going on since Jet Hot started becoming popular and people started seeing rust on their Jet Hot manifolds that were wrapped as well.

The wrappings both absorb and entrap moisture betwen the pipe and the wrapping.

My opinion is that if you use a QUALITY, TRUE ceramic THERMAL BARRIER coating (not a ceramic baked on paint like is 98% of them out there), then you will have no need to double it up with wrapping.

I don't want to get into a debate with what is a quality ceramic coating, but let's just say that a true thermal barrier is NOT CHEAP and they do not look pretty.

 

I do have a heat shield and the manifold is ceramic coated. It's just that during track days and autocross days, the engine bay gets really hot and if I can reduce it more, the better.

 

The only thing a ceramic coating will do is keep pretty parts looking pretty, and almost all coatings don't even do that!
Heat wrap is definitely the way to go, a thick barrier is what blocks the heat.

Don't worry about the wrap ruining your parts, it won't!

If you don't already have a turbo blanket, I highly recommend one!

 

How do you work that out when it is used widely in motorsport? I don't think teams chasing numbers and times are worried about their parts as you put it looking pretty.
Check my link further up the thread

 

Ditto. There is a difference between a thin ceramic paint (which the previous poster ise probably reffering to and familiar with), and a ceramic barrier coating as offered by high quality thermal coating companies. (not cheap, so most are not familiar with them)

 

ah... HEM.....

 

Hahaha, that's F'ing terrible!

OP is located in Las Vegas, not the salt pit they call Wisconsin.
We don't have that problem out west.

 

Exactly, teams chasing numbers. They will spend thousands to save fractions.
I have used 3 different types of coatings, and they just can not compare to a high quality wrap.
