For ceramic exhausts to work well they have to be coated from the inside. And for the ceramic coating to adhere a special wand has to be pushed down the pipes to bead blast the ID of the pipes, and a special spray gun used to spray the coating inside the pipes. Most shops are not set up for doing this so if you decide to have your pipes coated, ask what their process is for the insides of the pipes.
