I have had 2 sets of pipes ceramic coated, inside and out, Same vendor - Jet Hot, different locations.
1st set was coated when new, second set was about 20K miles.
Neither time did I get or ask for break in instructions. Naive maybe.
Both sets were installed and the bike run normally.
The 1st set after 20K miles or so still looked almost the same as the day installed.
The second set had a noticeable change of finish near the heads after 20 minutes.
Both coatings seem to be still well intact.
I don't remember the "color" and the choices have changed, but the original set was a bright or chrome finish (no chrome at all, just a name)
Mine looked similar to Fuzznuts' when his were done.
