I think Bernie has something swain coated. Bernie can you chime in.They seem to be the best for heat reduction from all the articles and maybe some videos I’ve read comparing the 3. From what I recall very often ceramic coatings peel and flake off over time. Jet Hot sounds to be the best if you’re concerned with appearance. Swain coat - seems to be on an entire different level … from what I’ve read. Not cheap tho. If I recall 2 exh manifolds where maybe $700+? I could very well be wrong. They have approx. $’s on their site. But size of product also is a factor to play in when it comes to cost.
