Ceramic Coated Header. DC Part# AHC6515

DC Sports 4-2-1 one-piece header systems deliver incredible low- to mid-range power gains, while improving ground clearance and reducing weight by eliminating the middle flanges. Our 4-2-1 one-piece headers are much lighter than stock systems and are on average two-pounds lighter than our two-piece systems. We dyno test them against the competition, and spend the extra time in R&D to ensure the best fitment for your vehicle.

DC Sports header systems are precision bent on our CNC mandrel benders using data acquired from our non-contact digitizing scanner. Our flanges are CNC machined, we machine-grind the flange mating surface to ensure a leak-free seal and use a robotic welder to attach the flange to the header pipes. Our state-of-the-art manufacturing process ensures superior quality and a perfect fit with every header system we make.

DC Sports 4-2-1 one-piece headers are available in 304-stainless steel, and in mild steel with a proprietary temperature- and corrosion-resistant ceramic coating. Once our mild-steel systems are completed in manufacturing, they are subjected to a thermal degrease and a preliminary sandblast to prepare the header’s surface for coating adhesion. Every ceramic-coated system is hand-painted to ensure an even application of coating. After verifying the proper thickness of the coating, the header is cured for proper bonding of the ceramic coating and then fine-blasted for a high-luster finish.
