I wanted some opinions on what benefits are provided from ceramic coated vs. The ceramic actually blocks alot of the heat if they are coated inside and out.
Ceramic Headers Vs Stainless Steel
Stainless steel vs ceramic headers. I had coated headers on my lt1 camaro and like one of the other posters accidentally bumped into one of the primaries with my hand after the engine had run for some time. The stainless header is a good choice for longevity but it doesnt have any insulation properties. Recently i have installed a cat back magnaflow exhaust on my 2008 silverado 1500 60l and am going to take the next step with headers. But because of the mild steel core it will eventually rust if the coating takes any abuse. I am going to be supercharging the engine within the next 9 mo. The ceramic label come from the fact that its mild steel with a cermaic coating not that the header is made of ceramic.
Stainless prevents corroision while the ceramic coating contains heat and adds more corrosion and stain protection. Also since the heat is staying inside the headers the exhaust gases will be hotter and will flow more remember as air cools it becomes more dense. Because of this coating they do not need header wrap. This keeps the header from rusting and insulates a lot of the heat. I also agree with the lower temps. Neither stainless or ceramic materials corrode so youll never have to worry about rust.
They dont rust so the coating wont flake off like it can on mild steel headers. Tacomx oct 17 2011 4. Stainless will radiate more heat into the engine compartment than ceramic coated headers will. The stainless steel will look all nice and shiny when you first buy it but after you install it and run the engine for about 10 minutes it will change color to a copper shade and stay that way from the heat. Ceramic coating stainless headers is the best way to go. Ceramic vs stainless headers.
Ceramic is cheaper and once it wears out you could always sand the old off and reapply a ceramic coating to the headers. Anywhere the coating is scratched will rust and the inside of the pipe will rust of course. And remember you get what you pay for especially in a header. I would go with the ceramic it wont last forever but it will keep the engine bay cooler than stainlessand you save 100. Ceramic headers can maintain their out of the box chrome like appearance for many years and the smooth surface makes them easy to clean. I also like stainless because i think they look better and they will last a lot longer granted if you buy the 700 dollar ones.
There will be substantial more radiant heat compared to coated. Stainless will discolor blue or gold depending on the temps but they will not rust. But stainless steel does discolor when the header gets hot and ceramic doesnt.
