The title says it all. I know that ideally they should be coated to keep heat out of the engine bay but, I don't want to spend money that has very little benefit. This is my DD that I don't think I will ever go beyond a 3.4 with. I see a lot of members that have ZZP, SSAC or speed daddy headers and just bolt them in. Can anybody educate me as to what I am gaining or losing either way? Please answer with more than a "do it" or "don't bother" response. I am trying to make an informed decision on whether or not to do it. Thanks for any help.
Edit: I'm going to research this topic for a little while and I'll continue to post information that I think may be useful. Please add to this discussion if you like.
