Do you mean stainless? I didn't know they offered ceramic. Either way, there is a stainless kospeed header on my girlfriends car (Honda accord). Nice thick flange and tubing appears to be good for the price. The only issues are the gaskets are usually junk and if you are looking from the engine side of the flange the ports aren't perfectly lined up with the primaries. With a little work you could easily smooth it out or just install it and call it good. Only other issue is on a Honda the welds can crack after a while if you have bad motor mounts or anything that would cause any header to crack. Happened to a friend of mine after 100,000+ miles so I welded over all the primaries and its still holding together.
