I noticed some guys are polishing the aluminum covers on the exhaust pipes and painting the actual pipes black. What type of paint are you using/ any normal heat resistant paint?

Never had much luck painting any type of exhaust until last year. I used an HTP with ceramic on the dump tubes and exposed pipe ends and it's holding up nicely.

surface prep and baking them in three stages seems to be the key.

The 2000 deg Rustoleum I used, had me baking it at 200 deg for 30 minutes w/ a 30 minute cooldown after. Then at 400 for 30 w/ a 30 cooldown. Then at 600 for 30 w/ a 30 cooldown.
The wife threw a rod when she say my entire exhaust in her oven.

tell her it could have been worse you could have thrown your primary in the dish washer ;)!
 
I just coated my slp's with VHT Flameproof paint with ceramic fillers. Supposed to be good stuff up to 2000 deg., and it's made for coating exhaust headers. You can cure the coating right on the sled by running a little bit, then more and more, etc. I haven't ridden it yet, but I've run it quite a few times, and it still looks new. Most auto parts stores carry it.
 
Ceramic coating is the way to go. I have tried so many different high temp. paints and application processes. I have not been able to find a paint that willlast for more than one season. Ceramic coating is a type of powder coating in which an powder coating is applied electrostatically to the metal parts. the ceramic powder is a mixture of ceramics and aluminum which when heated bonds very well to the base metal. A quality ceramic coating is VERY tough and durable. Ceramic materials are poor thermal conductors so the coating acts as an insulator therefore keeping the exhaust gases hot. The original aluminum covers on the SRX pipes are there for both thermal insualtion and sound deadening. The stock insualtion and aluminum covers provide much better thermal insulation than the ceramic coating alone. I had my SRX pipes powder coated and reinstalled the stock covers with the high temp cloth insulation.
 
The original high temp cloth type insulation was worn out. I found replacement high temp cloth material, cut it to fit the same way the stock material fit inside the aluminum cover, polished the outside of the aluminum covers and installed them the same way they were on the pipes originally.

What does the Ceramic provide that paint and primer does not. I'm guessing a bunch of heat suppresion. But how would this help w/ power ?

It has to do with heat suppression/ far less disipation of heat. Good ceramic coatings act as an insulator and exhaust stays hotter. Somehow the engine runs stronger a tad when this occurs.


I've tried sanding and repainting my SLP triple pipes numerous times. They always flaked off and rusted again. Rattle can paints just do not adhere tough enough tp withstand all of that heat! Then by January the paint is flaking off and the pipes look like crap again.


The only stuff that really works is a baked on ceramic coat in my experience..

Are those ceramic coated in the pic Mike? My VHT painted pipes look identical to those, same color and sheen.
