Ceramic Coating

[aussiegixxxr]

Hey guys, Anyone had any experience with this on exhausts and headers?
Basically i am getting my exhaust fixed, its got some scratches and so forth aswell, so im thinking about getting it coated black to match the frame and such....
Anyone know a rough price or any places that do it around syd west area...
Thanks

They are about 1/2 to 3/4 the price of "HPC coatings" and probably use the same stuff.

Some exhausts shouldnt have the internal pipes done as it messes with harmonic's. I spoke to the guys there and the coating is only a few thou..

I had a set on the RVF done which worked well. These bikes run a bit hot on the legs in heavy traffic which was significantly reduced

The silver coating is up to 700 deg (looks great) and the black (matt black) is up to 1000+ and for turbo applications. I had the black coating done to a couple of turbo headers and it worked well.

Full headers + link pipe is approx $200, high temp about $300. New headers are a little cheaper as they require less prep/cleaning/blasting. This also depends on the design, lengths etc. They only give approx prices over the phone but you can go there to get a firm quote.

JPS Automotive Blacktown 9622-2029 used to do it, not sure if he still does. I used to work for this guy and got involved in the coating. We used to do it to anything that was performance related. Engine parts, intakes and exhausts, was great stuff. You can get it coloured to a range of choices. I was suprised at how quickly the pipes cooled. We used to do some of the HQ racers and there is a small power gain from it in some cases.

It works a treat & the finishes you can get now are like chrome. Be carefull using anybody but HPC because I have seen some jobs that look great at first but few months later rust etc starts to form that isn't ment to happen. HPC do cost more but have a name to protect & if they do it then it will be done right first go. Do inside outside treatment because seals pipe completely & stops any chance of rust forming inside pipe & start to eat to the outside. Coating inside helps flow & can only help performance not decrease it, less heat better flow.

ok, awsome guys,
Basically though, ill be doing it simply to cover up a few scratchs on my slash cut exhaust (the loud one).... im getting it fixed up hopefully this week, the dents and whatnot, then i was gonna get it black to match the frame and shit....
How would i go about doing that seeing that it cant go inside the pipe itself because of the baffles and such...
here is a few pics so you know what i mean

So basically, im just after the pipe itself done on the outside, unless maybe a high temperature powercoating is a better option if there is a thing, Either way, it cant be done on the inside of the pipe where the baffle is...

Just one thing to think about with thermal coatings they will decrease the heat that is absorbed by the exhaust itself but they will actually raise the exhaust gas temperature ...

This is not a major problem but it will increase the velocity of the presure waves making any particular exhaust better suited for higher rpm with some small sacrifice to low end power.. Thermal coatings will potentially move the powerband up an extra 500rpm (approximately) :)

These are some good points, however I was given the details of competition coatings from my mates father in law who uses it on his road driven show cars. If its for a show car, specify as they will spend more time polishing it.

It doesnt actually decrease heat, it mearly sheilds it. I am getting a bit quicker spool up (turbo charged cars) which indicates less heat losses on the manifold. I.e its trapping the heat and running it hotter further down the path (to the turbo) as opposed to loosing heat energy from the pipes.

What is ceramic coatings primary function?? (performace or bling)

[aussiegixxxr]

well, performance but it also has bling factors, which is what im looking for to cover the scratched pipe...

I dont know if i can get it done or not seeing it being an exhuast, depends if they can cover the baffle entry and exit points.

Interesting info, thanks.

When i was involved everything got acid dipped to make sure it was clean, and then washed off, then coated, then put into a polishing machine. I suppose it would be possible to block the ends when it came to the coating and polishing, dunno about the acid dip though.

There is a place down at Taren Point that does ceramic,cant remember the address,but you'll find it in the yellow pages.The full system will cost you apprex $180.
If you think this process will hide scratches,you are sadly misstaken.It will actually magnify them.So make sure you prep it well.

Anyone got any details of who and where HPC is???

Get them coated on the inside as well.
I dont have them done on my bike (dont ride it enough), although my cars ones are done.

You know Ive had extractors on one of my old rotors crack because of the coating .. only time it ever happened to me though.

[Marcus]

I would do more research on coating the inside as it can change the pulses of the pipes.

Its only a 1/4mm thick so I guess it depends on a lot of things like bike, power, engine type etc.
