In 1987, American Honda commissioned DC Sports to develop a header for SCCA-prepped CRXs. What culminated was our first 4-into-1 header design, and it was so well received that Honda requested headers for other applications. That system (HHC5002) is the one that stared it all.
DC Sports 4-into-1 header systems are dyno tested to outperform all comparable header systems on the market. Extensive research and development goes into each system to ensure the best performance for your vehicle.
Our 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-into-1headers are available in T-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.
