Ceramic coated exhuast pipes

[Abe]

Has anyone done this, and if so, did it reduce the temperature under all the Tupperware (I think it is more of an issue on the 1300 than the 1100??)

I'm lead to believe that 100% ceramic coating is done in one coat and powder coating (ceramic) is done in several coats, though its classified ceramic coating.

I have use VHT cans in the past and worked well for the application.

Just food for thought, cost, effort and is it really worth it.

Cheers

Abe, I have done quite a few sets of headers in various colours for customers bikes. I get them done by a company in leongatha.  They do a great job. There is also another company in Castlemaine. 

Great effect especially if I get the chrome colour for naked bikes. Brilliant finish. They run much cooler, don't tarnish with heat like chrome.

The process coats inside and outside the headers. In theory giving a better gas flow than untreated ones. Although I have never dyno ran them before and after for results

Costs range from $200 to $300 a set of headers.   

[Abe]

Thanks for that Breharna,

So, one would think it would be around the $200 mark for the St's.  I have noticed that you can get this application done internally or externally on the exhaust system.  Would I be correct or close to say "internal" if the exhaust is new and still clean and "external" if the exhaust has been used??  They say it can reduce the "under bonnet" temp by 40 degree C.

Cheers

I had the stainless steel headers in the car (5.7 litre V8 holden) ceramic coated (just checked and it was $380 for both sets of headers). I think that was inside and out, not too sure.  The reduction in heat under the bonnet is really noticeable,  First time I looked it was as if the car had not been running it was so much cooler than standard.  The finish was like a dull aluminium, but you can get other colours.  The car runs on lpg as well, which is hotter, so I was impressed.

If you want to find out about it I can give you the contact at the exhaust place I used in Sydney.  Greg is quite willing to discuss such things.

Has anyone tries Exhaust Heat wrap ?

I actually bought a roll with the intention of using it.  Then the mechanic at Team Moto warned that by wrapping the headers I would be inhibiting their heat radiation (yep, that was the plan) but that would defeat the engine's design and potentially cause overheating of the cylinder heads.  So I returned it and took a store credit.
Summer's coming...

I would be careful about using exhaust wrap, as it can lead to premature rusting of the pipes.  Get an ST1100 if you are worried about heat 

[Wild Rose]

I really don't have a problem with heat from the 1300, I used to get a lot more heat from my previous bike a Kawasaki GTR1000
On the GTR-AUS forum a lot talked about Heat Wrap but I didn't worry about it 
On the ST1300 Highway pegs make a big difference

When I was in the exhaust game, we would advise against the wrapping of exhaust pipes. This was because the heat is trapped and the metal gets hotter, causing crystallisation, which can, cause fracturing of the exhaust pipes.

Ceramic coating is the way to go. We even have someone in the West who does it.

You can get the outside only or out and inside done. It does such a good job in transferring the heat that you can virtually touch the headers with the bare hand.

Malcolm doesn't ceramic coating have the same effect as exhaust wrap in terms of causing crystallisation?
If not, I need to get ceramic coating done on the headers on my van so who does ceramic coating in Perth?

Ceramic coating "seals" the metal to protect it.

Heat from the ST1300 engine........no, never experienced it!  But then it might just have something to do with where I live......ha!  Being an ex banana bender I feel sorry for all you guys, and gals, with summer just around the corner.

Thanks Couch, but you can keep your cold.  I'll suffer hot legs for maybe 6 months at the most rather than freeze my buns off for even 4 months.  As Rosie says, there's always the highway pegs!

[Couch]

But Biggles when it's cold, you just dress accordingly and it's not difficult to keep warm, (unless of course you're homeless and live on the streets) but when it's really hot it's near impossible to keep cool, unless you're sitting under an air con all day!  And believe it or not, it's not really as cold here as many people think. There are areas in Tasmania that get very cold, just as there are in all the other states, including Qld.  But here on the Peninsula where we live it's not all that bad. We have a few very cold days, but we have some absolutely magic weather as well, and that makes up for it. Whoops, I'm off topic again!

Budget price from CIC Ceramic for the headers on my 4 cylinder van outside only $330.

[Davoxt]

Just fitted my headers on with CIC ceramic chrome coating, waiting for my heated grips to turn up before fitting the tupperware back on and go for a test ride.
I can tell you they are still hot to touch (very) but you don’t feel much heat generating until you hand is close to a couple of inches away, compare to the stock headers you couldn’t get your hand much closer than a foot.

Looks fantastic!
Look forward to your report.

Emma chisit?

 

[Abe]

Thanks for taking the leap into ceramic coating of the headers   

Interesting to see if there is any temperature difference in the glove boxes (pie warmers).

Did you replace the gaskets???

Thanks

[Davoxt]

Coated on the inside as well and 4 new header gasket rings and 3 new muffler gaskets total cost $400.

Good thorough job.
Now for a few rides on hot days to see if it pays off.
A little exy if it's just the improved look of the pipes, but still worth doing just for that reason alone.

Watch this video about headers on a big block V8 about two month ago it's 18min long but around the 5min mark they start talk about the temperature difference between ceramic coated and painted.

Coated was 185deg Fahrenheit and painted was a whopping 873deg Fahrenheit.

WoW that's impressive 

[Malcolm6112]

Ceramic coating is recommended for boat exhausts, where heat can be an issue with boat parts. With the coating, inside and out, you can make a boat exhaust from mild steel. Not 316 stainless. Which can cost a pretty penny. The whole process seals the metal, hence no rust or degradation of the exhaust.

The exhaust always stays the same colour.

There is a little problem with the video.

With Infra-red Thermography, you have to be careful of a thing called emissivity. 
 
"The emissivity of the surface of a material is its effectiveness in emitting energy as thermal radiation. " http://en.wikipedia.org/wiki/Emissivity

The highly polished shiney pipes won't radiate Infra-red as well as the black painted pipes.  At 185 °F they are probably reading the temperature of teh engine block reflected off the pipes.

If you were to paint a small part of the shiney pipes with matt black paint, you would be able to see the real temperature.  We did an experiment in a Thermography class where we had a shiney coffee tin in which boiling water had been poured, yet the Infra-red thermometer only indicated about 25 °C.  Once we stuck a bit of black electrical tape to the side it indicated 99 °C (the water had cooled a little and a thermometer in the water also read 99 °C)

Emissivity is one of the reasons Infra-red cameras can't see through glass, and the glass acts like a mirror to Infra-red and I've seen my own thermal image reflected in a window.

I'm not dismissing Ceramics at all, just pointing out their figures (in Farenheit) are possibly in error. 

Depending on the ceramic and its thickness it can act as a heat barrier (Space Shuttle) and the surface can lose its heat rapidly to air keeping the surface of the ceramic cooler while the inside is still very hot.
