Rugged Ridge performance exhaust headers for 4.0L Wrangler engines are now available in high temperature Metallic Ceramic finish! Not only does our ceramic coating look great, it protects against corrosion and thermal fatigue, while increasing horsepower and extending the life your of header. Ceramic headers retain heater better than their chrome or stainless counterparts, and we all know that a hot pipe is a happy pipe. Retaining the exhaust heat improves the air density in your cylinder head's combustion chamber for enhanced air flow. This improved flow increases the exhaust gas exit velocity, and cuts down on your underhood temperature, resulting in performance gains. Our coating is the best finish on the market and offers thermal protection up to 1,500 degrees. The finish won't flake off like paint or blue like chrome or stainless. It also cools to the touch more quickly than standard headers. Backed by a three year corrosion warranty.
