DC Sports 4-2-1 two-piece header systems deliver the same performance as our one-piece systems in a two piece design that eases installation. Our 4-2-1 two-piece header was rated “Best of the Test” in peak power, peak torque and average power gain by Sport Compact Car magazine. All of our 4-2-1 two-piece headers are dyno tuned and tested against the competition to outperform all comparable header systems.

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 two-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.
