The DC Sports stainless steel header replaces the restrictive cast manifold on 1994–2001 Integra RS/LS/GS models using a 4‑2‑1 layout with four equal-length, mandrel-bent primary tubes that merge into two intermediate pipes before converging in a single collector. This design promotes optimal exhaust scavenging by timing the reflected pressure waves from paired cylinders to improve mid-range torque between roughly 3,000 and 6,000 RPM, thereby smoothing throttle response and enhancing real-world drivability.
Unlike a 4‑1 header, which tends to boost peak horsepower at high RPMs but sacrifices low end grunt, the 4‑2‑1 configuration broadens the usable power band. It delivers more consistent torque across the rev range, making it an ideal match for daily-driven B-series engines. Plus, with its compact two-step merge, it often fits more neatly under the chassis, preserving ground clearance. Built from corrosion-resistant, hand-TIG-welded 304 stainless steel, this header keeps exhaust pulses smooth and your engine bay cooler, without straying too far into race territory.
Add the optional high-temperature ceramic coating, rated for up to 1,200°F, to keep exhaust heat where it belongs, inside the pipes. By holding heat in, exhaust gases move faster, helping the engine breathe better and make more consistent power. It also reduces the heat radiating into the engine bay, keeping intake temperatures cooler and everything under the hood happier. The coating withstands endless heat cycles, helping the header maintain its clean finish.
- Immediate gains you can feel – broader mid-range torque and a crisper top-end pull
- Cooler engine bay – the ceramic coating sheds heat, guarding hoses, wiring, and your intake charge
- Street-legal confidence – 50-state C.A.R.B. EO compliance means zero inspection worries
- Built to last – CNC-machined flanges resist warping; double-welded seams stand up to years of spirited driving
- Perfect match for bolt-on builds – pairs flawlessly with stock or aftermarket cat-back exhausts and intake mods
