Anyone have any issues with surface rust on their TTI ceramic coated headers ? I have had these headers for about 6 years , after the first season the passenger front tube that goes across the top & down has had surface rust ( probably over the hole surface that shows ) . I am ready to pull the engine to freshen and will be seeking a way to re-coat . Kind of a touchy issue since we had to pay so much for them you would have thought they would have lasted . Just checking to see if I am the only one with the problem . Gary
