DC Sports 4-into-1 and 4-2-1 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.

DC 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

# Every DC Header system is dyno-tested for maximum performance
# CAD-rendered, race-inspired 4-2-1 design emphasizes low and mid-range power for street/strip applications
# DC Sports One-piece design improves ground clearance and reduces weight by eliminating middle flanges-significantly lighter than stock and two pounds lighter than two-piece systems!
# 100% 304 Stainless steel construction including the flanges (polished or brushed), or mild steel with ceramic coating
# CNC mandrel bends with robotically-welded fittings deliver perfect fit
# NOT FOR STREET USE OFF ROAD USE ONLY
