Anyone have any experience with their products?

I'm looking at their ceramic coated headers for my 1970 SS 396....looks like a decent price...made by Petronix.

I have a set of shorty small block headers, Had them around 3 years and they seem built good and the ceramic coating is holding up well. Every spring I take WD-40 and steel wool to them as they get really small rust specs on them but they clean up nice. Nice thick flange also.
