at last my dealer called me yesterday and told me that my akrapovic exhaust is waiting for me. however i want to modify things further and ceramic coat the header pipe. i decided that the exhaust wrap is not worth, since it encourages corrosion. i believe that a pipe that is so close to the suspension (as well as other sensitive parts i.e. brake lines, cables) should be somehow thermally insulated.
anyone has done something like this on his/her bike?
:nerd:

100% correct on the wrap. Works INCREDIBLY well, but traps moisture in a very hard environment and will destroy steel in no time.

Unless you map the bike after intake AND exhaust, your gains will be minimal and speculative.

Save your cash, just put the pipe on and go. PLENTY of air flow and space back there. Maybe find some gold foil and discretely cover the inside edges close to the pipe? Would kinda look cool. Might do that if I decide to go with the Hypercone... Hmmm...

you got me wrong, i am not after any improvement in terms of horsepower, i am aiming at insulating the suspension from heat. i dunno maybe i am exaggerating but ceramic coatings are supposed to dissipate heat faster and thus be cooler.

Not quite true... The ceramic coating works as an insulator, like the exhaust wrap but much better.

It can improve performance by keeping the exhaust gases hot and therefor faster flowing. It's pretty common racecar to ceramic coat the inside of the exhaust manifolds to cut engine bay temps and improve performance.

i thought that it was a matter of insulation but maybe you are right: ceramic materials can store a great amount of heat
Do you not mean powder coating? I get all of my cars ceramic coated which is typically just a top coat over the clear to protect the paint and such.

I have had pipes, wheels, cosmetic items and such powder coated all to great success!

It's basically powder coating with a ceramic layer. If you Google HPC (high performance ceramic) coating, you will see what I'm talking about.

I wrapped my header, mostly for the looks and because I could.


I installed the wrap by removing the header, wrapping wet wrap around it, re-installing it and running it for some time to dry out the wrap.


I made sure the wrap was totally dry and removed the header and sealed the wrap with high temp clear coat.


Note: this was the stock header, if it corrodes, it gives me an excuse to get an akra.

You could look into having someone Cerakote it like firearms, it can be used on wheels, exhausts etc.


I don't know why you would want to do that as pipe is stainless and turns a gold-ish color. The only people I know of that wrap pipes is the cruiser/Harley crowd to keep the pipes from burning them or to look like it just went thru WWII or the zombie apocalypse.


I have not had any heat issues on my GS with a Akrapovic CF unit. There is so much room back there that there is no way it could affect your suspension.

although the zombie apocalypse scenario gives me ideas...no, i don't want to spoil the original look of the pipe. i am just worried about the heat, anyway i contacted a specialist in England and he told me that for ~200 euros i could coat the pipe. he said that his product offers a 25% heat reduction. i don't know if it's worth the trouble..

I don't think it gets blistering hot in England (I do not know). What color are you thinking of coating it?

the technician i contacted is in England, i live in Greece. i don't think that the ambient temperature affects the pipe that much. i was thinking about black coating but finally i don't think it's worth the trouble, i ll trust the original BMW design and we ll see what happens..
