It will get tiny pock marks in it from road debris. Titanium will hide it, black will not.
I have a lot of experience with ceramic.
Also keep in mind, there is a lot of black on this bike, using black ceramic that is close to, but not a match, for the other black, could look goofy. I always try to either match perfectly, or make it an intentional mismatch, that compliments the bike.
Think about how the silencer is attached to the header/midpipe as well. If there is a long connecting pipe that is permanently attached to the silencer, that could be a problem. The ceramic typically goes into an oven to cure, you don't want say a carbon fiber silencer in that oven. The coater will not place a carbon silencer in that oven. That means disassembling the silencer to disconnect that connecting pipe, so that it can be coated, then reassembled afterward.
I see the end cap on the motor side is stainless, and a 3-4" pipe attached to the silencer. Your choices are:
Air cure ceramic
Don't coat the end of the silencer
Disassemble the silencer to separate the end cap, coat, then re-rivet
