Recently bought a set of ISR headers, getting them ready for install. They're going on my daily driver. Should I send them to JetHot to get coated? Use VHT FlameProof Ceramic paint & primer? Do I heat wrap over the coating? Should I leave them raw? I live in NY, where winters see a fair bit of salt. I get mixed info for this kind of stuff and I can't find any concrete information online. I plan to get tuned with the very controversial use of a flame map. What do you think? To wrap or not to wrap? To coat or not to coat?

 

Coated it, and also make sure the flanges are not warped before installing

 

I had mine ceramic coated

 

Not this car (yet) but Jet-Hot on turbo manifolds and downpipe of my RX7 held up beautifully. Didn't wrap because the temp reduction was already significant.

Wrapped a stainless header for my Jeep and almost every weld failed. YMMV
