Ceramic Coat stock R3T exhaust exchange pipe.

[Paul Bryant]

So you think I should skip the headers, I agree that they don't get that hot. I am sure that the heat I am feeling is coming from the exchange (mid?) pipe. Ceramic coating, inside and out, would have to help with that.

Andrew, I don't think you would be feeling heat from the exchange pipe, if what you are calling the exchange pipe I call the cross over pipe.
This is the pipe that "cross's over" to the L/H side of the bike.
This is down under the bike.

Well, I feel a lot of heat coming up from below the seat on the right side. Not enough to melt my clothes but enough to make it uncomfortable in 90° (32° C) + weather.

I don't notice it much at all when I'm on the freeway but so far the majority of my riding is city miles commuting back and forth to work.

Ceramic coating wont hurt. You could knock up something like this for the headers

I dont think it does anything and its not a problem on the stock exhaust system

I don't think so. The heat you are describing is a result of the CAT in the mufflers. That's how they work. They get red hot inside in order to burn any unburnt gases that did not get burnt in the combustion chamber. By virtue of the fact that it's a 3 dimensional sieve, it is a restriction to the flow of the gases. To contain that extra heat, the internal canister that encapsulates the CAT is twice as thick. They are way heavier than TOR's.

The extra heat that the CAT creates then migrates forward to the crossover you are referring too and this is why you are feeling it in that location. As soon as you move from a stop, the external flow of air (and internal flow of gas to some degree) cause the heat to migrate rearward towards the CAT
again.

I don't think ceramic coating will make a noticeable difference for you and it's money you could save towards the header pipe. If you can afford the TOR's do that first, and if you can't and/or prefer lower end torque and quieter (closer to stock) sound do the de-cat. Either one will be cooler than ceramic coating the pipes in my opinion.

Thank you for your opinion. The way you describe the heat build up in the CATs and the way it would move forward while stopped makes sense to me. So as much as coating the crossover pipe might help, it wouldn't be dealing with the root cause.

I'll hold off on getting anything coated, research de-cating stock mufflers, and save for some TORs.

It's good to know that they make a difference in heat levels. Thanks!
