Patriot cast iron manifolds designed for GM LS engines offer a wide variety of fitment applications maximizing engine bay clearance. They also incorporate a sealing dome and ships with a pair of 304 series stainless steel reducers to help route your exhaust system with more adjustment options than the competition--no more expensive GM gaskets needed to get you on the road. Patriot cast iron manifolds will fit many of their LS engine swaps. Finishes offered for Patriot cast iron manifolds: * Metallic Ceramic Thermal Barrier Coating (MCTBC), which is polished with a vibratory finishing process that not only produces a high-luster aluminum appearance, but also compresses and activates the coating, which increases the surface hardness. The finish is 60 percent more corrosion resistant than an unpolished surface, easy to maintain, and will last for years under normal operation conditions. MCTBC also protects and extends the life of headers by creating a thermal barrier (heat-resistant up to 1,600 degrees F) that significantly lowers under hood temperatures and protects the substrate metal from thermal fatigue. * Hi-Temp black coating is an affordably priced alternative to their MCTBC. This finish provides good corrosion and heat protection when compared to many of the "cheaper" header finishes being applied by our competitors. * Raw cast is available for individual customizing
