Ceramic Coating Ti Pipes

I have looked up previous posts on this topic, but after more clarification.

I have an Akrapovic full Titanium exhaust and have made enquiries with a local company that does ceramic coating of motorcycle and car exhausts. I am looking specifically for the headers and collector/midpipe sections to be done. This is to help lower radiated heat from the exhaust, and potentially keep the engine temps down a bit.

I asked them if the ceramic coating can be done on the inside only or both inside and outside, and if there is any benefit to one or the other.

They have replied to me stating they don't do the inside of the pipes as they cannot ensure there won't be any "runs" in the coating, and there is a potential of "reducing exhaust flow due to narrowing of the internal diameter" when applying the coating. Also they said it's hard to guarantee the cleanliness of the pipe's interior prior to coating.

Anyone have opinions or experience on this?

Don.

Both the inside and outside of your pipes can be coated together or separately. The most significant improvement will come from coating the outside and any portions of the inside that can be done properly. Trying to coat the inside only, is possible much like some chrome pipes are coated to reduce blueing on other bikes but MUCH more difficult.

The problem with this process is that in order to prepare the inside surface for coating you have to mask the complete exterior surface which becomes VERY difficult. Potentially impossible if you have to thermally degrease the pipes in order to remove leftover mandrel grease on the ID of the pipes as baking them could change the color look / color of the TI surface. The fear of significant runs or reducing the ID of the pipe is pretty insignificant.

Thankyou very much for that information! Good to know the main benefit is achieved from external coating, with perhaps some minimal internal coating, I guess the first few inches/centimetres of the pipe inlets.

Would it be advised to mask off end sections of the external piping, such as where the headers fit into the engine block exhaust ports, if there may be a fitment issue due to being overtight with the ceramic coating?

Cheers,

Don.

That would be a question best answered by the shop actually doing the coating. If they don't ask, DEFINITELY bring it up. It ultimately depends on the particular type of ceramic coating being used, the substrate of the pipes you are coating and the fit of your current slip-fit pipes.

So if you have mild steel pipes you want to coat as much of them as possible. With stainless and TI pipes this isn't as critical. In either case, if the slip-fit of the uncoated pipes is tight, then you're definitely not going to coat that area. Conversely, if the fit is on the loose side, coating them is going to work in your favor and reduce any corrosion from occurring on that joint that would make dis-assembling the pipes at a later date more difficult.

On double slip type pipes like the collector below or many Ducati pipes its a case by case basis. Some are loose and others are really tight, many times as a result of the tubes NOT being totally round after bending / memory or other processing.

Thanks again, I will make sure these questions are asked when I take the exhaust in for coating.

Interesting. I'm looking to get a new system for my bike and one worry is that I'm also changing the A models single fan to two fans that are designed for motorcycles but are heat resistant plastic. For peace of mind I'm going to wrap the headers but this sounds much more permanent and tidy solution.

How much less heat is radiated from ceramic coated pipes? Is it worth it?

I have never even thought about this and want to know more about the benefits.

I found this helpful but I have no idea of how much difference in temperature and power could I expect?

I had my akra (header and midpipe) coated, outside only, it is the SS model. I did it in anticipation of using a chinese fairing set which I thought could be heat sensitive.

Weedy64, how have you found the coating as far as keeping the bike cooler? I still haven't got it done yet as costs in Aus. are quite steep, at least from the companies I have looked at. One company I was thinking of actually send the pipes of to Britain to get done!

I have not run it yet.

Im near Vancouver, its an 04 (dual fans) so it doesnt really overheat anyway. It was for performance and fairing protection that I got it done. Bike ran normally heat wise so I don't think Ill notice any great heat reduction, and I just cleaned the rad so there is no way I will have any great comparative data for you. 220 CAD$ I think.

Too bad your not closer you could try em out.

Thanks weedy64, yes it's a pity I don't live close to a lot of bike product related companies that are prevalent in USA and Canada! It makes it more expensive in Aust.

This is something I still want to do, but other family priorities have reared their heads lately that have put a couple of bike projects on hold.

Still look forward to read what you think of the coating at a later date.

Cheers,

Don.
