My headers are mild steel and jet hot coated. The jet hot burned off and the headers rusted through where the four pipes come together. I had them welded and repaired and they are now high temp painted silver and they look a lot better. If they get dirty another coat of paint has things looking good again.
My external side pipes were 100% stainless baffled pipes that were extremely hot and sounded tinny.
the external pipes are now mild steel hot dogs with stainless outers and a 1/4" air gap between the hot dog and the outer stainless skin. These pipes have a deep rumbling growl and sound great but don't get hot enough to burn skin
Cheers,
Bryan
