Gents, I'm about to purchase a set of Kooks 1-7/8in headers for my 14 GT500. I've already decided to have professionally ceramic coated by Jet-Hot, mainly just to keep the under-hood temps down (based off my past experience with my 04 Cobra....may she rest in peace ). My question is how hot are the average exhaust manifold/header temps on these cars? Jet-hot has 3 different heat rated options for coatings, 1250, 2000, and 2500 degree. They recommend the Ultra Extreme 2500 for supercharged applications, but I'm wondering if this may be a bit overkill for my particular application.
For a little background, the car is basically a FBO (CAI, TB, Pulley, and soon headers and catted h-pipe). Also, the car is a garage/dyno queen and does not see the track. I basically take it out every now and then when I'm feeling "ornery"...LOL.
