WOW Jeff!

I need to take lessons from you!

It's all about the details.

Looks good!

 

No need for lessons, got divorced but kept the house and kids. Oh ya, and my scooters. Best thing she ever did for me!

Cool Duane!
But I guess you know what that means.
Wrong picture on your profile!
Details, details!

Just have to wait till June for some new pics

Thanks to all who responded to my questions.
I really appreciate the feedback.
There are two things I don't understand about the coating.
First, how do they get the coating all the way in to the header, or is it just the part that is visible? and
Second, how can this coating result in what sounds like significantly lower temps coming off the header?
I am hoping one of you who understands the science behind the claim that it lowers temps can explain it to me and maybe others who don't get it, because it sounds like magic.
Thanks again, I'll hang up and wait for an answer.

It works cause hot is always trying to get cold. I did not make that up, the universe did.

It is natural to confuse heat with temperature. That’s because the more you heat something, the higher its temperature becomes. But heat and temperature aren’t the same things. Heat is a form of energy. A difference in temperature causes heat to flow. Just remember, heat is something that flows and temperature is what makes heat flow.

I believe they coat the many things they coat with plasma sprayers...Like many things in industry..

I know these silly things because I am in the cold to hot to cold business. Capece?

The only pic of a plasma spryer I could find...sorry

Magic?

The coating acts like a thermal barrier and slows the ability of heat (energy) to move to cooler areas.
It keeps the Radiated heat down from the manifold, but does not reduce the exhaust temp (in fact it raises the temp of exhaust gases over a reg manifold)

miker, you really f$%*ed me up here.


i thought i knew what is going on.





TN


it works, trust me.

There are only 4 rules.


The Zeroth Law say there is no heat flow between objects that are the same temperature
The First Law is that heat cannot be created or destroyed
The Second Law is "Entropy" is a quantifiable measure of how evenly distributed heat is.
The Third Law says 100% efficiency is impossible.

Or:

The First Law says you can’t win.
The Second Law says the best you can do is to break even.
The Third Law says you can only break even at absolute zero.

Wow, you guys know this stuff!
I am impressed.
Thanks for the explanations, I think I get the science now.
So, only three more questions and I am done.
First, does, this coating in any way effect fitting the pipes back to the exhaust ports or the positioning and reattachment of the heat shields to the pipes?
Second, and probably the most important, does this coating really lower external temperature at the point of exhaust from the cylinder heads?
Lastly, if the heat is prevented from radiating out of the header pipes and crossover, is this going to create some sort of issue downstream at the mufflers that could result in chrome discoloration?
Thanks again, you guys are awesome.

It helps scavenge the heat , yesLastly, if the heat is prevented from radiating out of the header pipes and crossover, is this going to create some sort of issue downstream at the mufflers that could result in chrome discoloration? Possibly, based on what material the muffler is made from and the quality of the seal at the joint.Thanks again, you guys are awesome.

Was disappointed when I opened the package last night. While the outside color is nice, it appears there is very little if any ceramic coating on the inside. Just a dusting in places.  I thought the ceramic is what was to channel the heat out the mufflers. Without it I don't see how it will improve the heat transfer. Please straighten me out if I'm wrong. ( It went to the shop today to be installed, so can't send it back and can't get pics)

[Keats]

The ceramic coating is a barrier for heat transfer,
heat will be retained inside the pipe and go out the exhaust.

not that sure you can tell the amount of coating by just looking at it (certainly not on the inside)

not sure if you could tell the coating was working without some temp measurements before and after anyway?

hot pipe before coating and hot pipe after coating.

hot is determined by what burns and inflicts pain!   you cannot hardly determine the difference by feel between 500 deg and 800 deg ? both hot

[Indenial]

Is there ceramic in the outer coating as well?

[Keats]

yes, that silver looking material is the ceramic coating Inside and outside

Got the extream sterling on header crossover and clamps for 190$ the local dealer that does a lot of turbo work on imports swears buy it and said you can use a mild chrome polish to inhance the looks......
