I would also like to make a comment on this.... This is THE best thing to do to your exhaust system (especially the manifolds) to preserve them, keep them from rotting out on you. If you can't afford to or even want to ceramic coat the parts, you can use POR-15's product that is a paint on solution. This is a different type of heat resistant paint since it can withstand 1400 degrees continuosly. Some high temp coatings only claim that it can handle up to a certain degree, not continuosly...meaning it will burn off if exposed to a certain temp for to long. It also needs to be heated to 300 degrees to fully cure. They have two colors, manifold grey and Aluminum. I used Manifold grey on my Mnaifolds and let me tell you, they look like they were just manufactured. A small can of this stuff goes a LONG way. Enough to do your entire exhaust system...and it cost $15. I am pleased with the results and if you prep the metal properly, the paint will never burn off. You can paint the parts on or off the car, but I recomend taking them off so you can get to all the areas of the parts. I will post pics on my site if anyone is interested.
