DC Sports Ceramic Coated 4-1 Header for 02-06 Acura RSX Type-S (K20A2) – AHC6514
Wake up your K20A2 with real gains, cleaner VTEC crossover, and less under-hood heat using the DC Sports 4-1 ceramic exhaust header for the 02-06 Acura RSX Type-S. This RSX Type-S equal length header replaces the bulky cast manifold with thick-wall T-409 stainless, mandrel-bent primaries, and a race-style CNC-machined 4-1 collector. You get better scavenging, lower backpressure, and repeatable dyno-proven gains in mid-range torque and top-end power—while staying 50-state legal with a DC Sports RSX header that’s CARB approved under EO D-370-14.
Why this header actually feels faster
True equal-length, large-diameter runners sharpen throttle response and let your K20A2 pull cleanly and harder through VTEC.
Ceramic coating (inside and out, rated to 1,200 °F) cuts radiant heat, helping keep plastics, hoses, and intake temps in check—especially in traffic or on hot track days.
Thick 3/8" flanges, precision mandrel bends, and quality welds help prevent leaks and warping so you’re not chasing exhaust ticks later.
OEM-location secondary O₂ bung and factory-style two-bolt flange let this DC Sports exhaust header RSX piece bolt to the stock cat, A/C, and emissions gear—so your 2002 Acura RSX ceramic header upgrade stays daily friendly.
Street-driven, enthusiast approved
This Acura RSX 02-06 header gives you that classic K-series rasp and growl when you’re on it, without turning your commute into drone central. Run it with a stock or aftermarket cat-back for a solid RSX Type-S exhaust upgrade, then add an ECU reflash to pick up even more power. We run this same DC Sports header Acura RSX setup on our own cars, so we know what it does in the real world—autocross, canyon runs, or just hammering an on-ramp.
