If you are really keen on reducing underhood temperatures then look at having this actual thermal ceramic coating applied.
Difference between stainless steel and ceramic coated headers.
Provides the biggest horsepower gains when compared to other exhaust insulation methods.
A ceramic header coating also provides protection against the corrosive materials in the exhaust.
A good ceramic coated stainless steel header will out perform an uncoated stainless header by keeping the exhaust gasses hotter for longer which means the exhaust gasses will flow faster which leads to better scavanging.
Ceramic is a highly durable substance that resists corrosion and stands up to a large amount of abuse.
Im scared that in a few years they will rust and.
Recently i have installed a cat back magnaflow exhaust on my 2008 silverado 1500 6 0l and am going to take the next step with headers.
Compared to a standard painted surface a ceramic coated header can run up to 50 cooler surface temperature.
Narrowing the gap even further are those who opt to have their headers coated at a local shop.
In other words ceramic coated headers look and function the same on mile one as they do on mile 300 000.
Ceramic coated headers ceramic coated exhaust parts this is a spray on finish that s infused with heat insulating ceramics.
The ceramic actually blocks alot of the heat if they are coated inside and out.
Stainless headers cost significantly more than mild steel headers closing the price gap between them and ceramic coated mild steel headers.
Ceramic coating takes the heat and retains the superior finish.
Ceramic coated versus non coated.
It is not a diy solution these exhaust parts are coated at the factory or sent to a facility with the proper equipment.
The parts are prepped coated baked and polished in a controlled environment assuring a perfect finish every time.
Stainless steel headers within the external engine forums part of the lsx technical help section category.
I am going to be supercharging the engine within the next 9 mo.
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.
This is a discussion on ceramic coated vs.
How long do lt headers with ceramic coating last.
But if your headers are produced from stainless steel it s a waste of money basically it s an up sell.
