For all of you who have headers installed, i have some questions. Im thinking of purchasing DC Ceramic coated 4-2-1 headers to complete my bolt on set up.

Which type of headers do you own, ceramic or ss?
How long have you had the headers for?
How is the discoloration of the headers as time passes?
With the header, how hot does the engine bay get?
How hot does the hood become with the headers?
Is the gain significantly noticeable?
do headers increase noise level? if so, by how much?
what are the advantages and the disadvantages of having headers?

Thanks.
