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.
