HEADER 409 SS 07-10 JK 3.8L

These custom designed high quality Rugged Ridge headers are constructed of 409 stainless steel for a long operating life and the ultimate in performance. All Header flanges are welded 360 degrees to stand up against the hottest conditions. Each Header is designed to prevent thermal fatigue while increasing horsepower though heat retention. Retaining exhaust heat improves air density in the cylinder head's combustion chamber for enhanced air flow. This improved flow increases the exhaust gas exit velocity, and cuts down on your under hood temperature, resulting in performance gains. Each complete kit includes manifolds, gaskets, hardware clamps and is backed by a three year limited warranty against corrosion.
