Headers, TTI or Doug’s?
Do you have to rust proof Doug's in the off season?
I just walked down and looked at the Doug's on my car installed 2000ish and my son's installed 2005ish, both are slightly duller than when installed (Ceramic). No protectant .
The TTI owners were pretty quick to mention the rust, no mention at all from Doug's, I regularly service these vehicles .
I will recommend you leave the plastic bags on as long as poss, as protection from finger marks that bake on when fired up.
Wipe the finger/hand prints off with brake clean or smilar .
Far superior quality and modern design than the days of old, with poor ground clearances and plug access .
Good Luck .
