Have any of you "rich" guys out there had your tube headers (or cast iron manifold exhaust) ceramic coated? Many of the online testimonials I've read praise the results.

It doesn't come cheap. This company

gets 140.00 to do full length I6 street headers inside and out. That's pricey.

Ken, Tony, chiphead - you guys are billionares a million times over. Have you had this done?
