The DC Sports NHC4203 is a 4-2-1 one-piece ceramic header engineered to enhance your Nissan 240SX's engine performance. The flange mating surface is machine-ground to ensure optimal gasket contact. Its construction from 304 stainless steel tubing and a proprietary ceramic coating provides excellent resistance to temperature and corrosion, finished with a high-luster appearance. This header is specifically tuned and dyno-tested to maximize your engine's output, aiming for gains of up to 10 HP and improved torque across the RPM range. The 4-2-1 design emphasizes low- to mid-range power gains, making it ideal for street/strip applications. It also contributes to improved ground clearance and reduced weight compared to stock systems. Installation is facilitated by the inclusion of all necessary hardware and comprehensive instructions, ensuring a factory-like fit. All DC Sports header applications are CARB-Exempt and 50-state legal.
