4-2-1 Ceramic Exhaust Header - 2PC - AHC6016

4-2-1 Ceramic Exhaust Header, Two Piece

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 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 has several 50-state legal header designs to choose from. These include a race-inspired 4-into-1 design that optimizes mid- to top-end power, a lightweight, one-piece 4-2-1 design that provides maximum ground clearance and emphasizes low- to mid-range power for street/drag applications, a two-piece 4-2-1 design for easy installation and unmatched low- to mid-range power, and a 3-into-1 design for V6 applications. We are also proud to offer "Race-Only" headers in 4-into-1 and 4-2-1 designs (not C.A.R.B. exempt) for off-road applications only.
