How to ceramic coat an exhaust
Ceramic coating an exhaust is a straightforward process. (Motorcycle Exhaust image by Billy Tait from

A ceramic exhaust coating acts as an insulating layer on the exhaust pipe that transfers heat by moving it from inside the vehicle to the outside in an efficient manner. Adding a ceramic coating to an exhaust pipe is a straightforward process, but there are several steps and specialised tools that are involved. The main tool necessary is a paint sprayer or airbrushing machine. This project will take about one or two days to complete.

  1. 1

    Remove the exhaust pipe from the vehicle using a socket and ratchet set. Move the exhaust pipe to the location where you will clean the exhaust pipe before coating it with the ceramic coating.

  2. 2

    Clean the entire surface of the exhaust pipe, inside and out, with a degreasing cleaner. This will remove all grime, grease and oil from the surface of the exhaust pipe. Remove any difficult to remove grime with a steel wool pad. Rinse with clear water and dry with old towels.

  3. 3

    Wash the surface of the exhaust pipe in trisodium phosphate. This chemical will remove all traces of grease from the surface of the exhaust pipe and it will also help the ceramic coating stick on the surface much better.

  4. 4

    Spread tarpaulins over any surface that you do not want painted. Hold them in place with masking tape or heavy objects. You can paint the ceramic coating on indoor or outdoor. If you choose to paint outside, make sure that there is little to no wind on the day that you paint. Ventilation is a must indoors. Open any doors and windows leading to the area.

  5. 5

    Wear eye protection and a respirator. Fill the spray gun with the ceramic coating spray. Spray the inside and outside of the exhaust pipe with the ceramic coating. You will probably have to spray half of the outside, then flip it over and paint the other side once the ceramic coating is dry. Allow the coating to dry for one hour.

  6. 6

    Replace the exhaust pipe inside the vehicle when the ceramic coating is dry. Turn on the vehicle and allow the exhaust pipes to heat. This sets the ceramic coating and prevents it from flaking off. Allow the exhaust pipes to remain hot for about 30 minutes. Allow the exhaust to cool.

  7. 7

    Remove the exhaust and repeat the application process two more times. This gives the exhaust pipe a thick, insulated ceramic coating that can last for years.
