This high temperature paint is the closest we've found to the original Porsche color. It comes in a 12 oz. spray can and is very easy to apply. It will withstand temps of 1200 degrees and can be easily touched up.
It should be applied over bare metal. New Dansk mufflers should be stripped with thinner or blasted since their original coating is not heat proof.
One can is enough for two mufflers and J pipes.
