tti's turned gray?

I've got the nickel plated ones on my duster,they're still looking good after 3 years,i also polish them by hand before the season starts each year...

Nickel plated would be the chrome ones right?

I realize that the chrome ones turn blue but the main objective in my book would be defeating rust. I really don't care what my headers look like as long as they are not rusting. Rust means they are down to bare metal. I mean if the chrome don't rust at all why would you buy the ceramic coated ones if they eventually start rusting?

I'm going to get some TTI headers one day mainly for the fit but still undecided about the chrome or ceramic coated. If 345man is having trouble with the discoloration then I'm leaning toward the chrome ones.
