Tom says racers do it after running them to get them sort of normalized. Others say 321 doesn't need it. Kevin, I had my 321 SS exhaust ceramic coated by a company called Jet Hot. They have a ceramic coating that will stand 2000 degrees. The big advantage that I see to the coating is that, it keeps the exhaust pipe from absorbing as much heat from the hot exhaust, and also it radiates a whole lot less heat inside the cowling. It was also pretty cheap to do. As I recall, about $50. I've been very pleased with it. Here's a link to their website, if you are interested. http://www.jet-hot.com/ Steve Brooks ------=_NextPart_000_008C_01C51F49.91DCAF80 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable
