DC Sports Ceramic Header for 00-09 Honda S2000

DC Sports HHC5020 Ceramic Header for 2000-2009 Honda S2000 (AP1 / AP2)

The DC Sports HHC5020 is a direct bolt-on performance exhaust header built specifically for the 2000-2009 Honda S2000 - covering both the AP1 F20C (2000-2005) and AP2 F22C (2006-2009). T-409 stainless steel construction, a true 4-2-1 merge collector, and a 1200-degree-rated ceramic thermal barrier coating make this one of the most complete bolt-on exhaust upgrades available for the platform. If you want your F-Series to breathe the way Honda's engineers always intended - and then some - this is the header to do it with.

Why AP1 and AP2 Owners Run This Header

• True 4-2-1 merge collector layout - Equal-length runners feed a stepped collector that builds mid-range torque without sacrificing the top-end pull the F20C and F22C are famous for. You feel it on the street and on the track.
• 1.75-inch primary runners stepping to a 2.5-inch outlet - Mandrel-bent throughout, so there are no crimped bends killing flow velocity. The factory manifold restriction is completely eliminated.
• 1200-degree-rated ceramic thermal barrier coating - Keeps exhaust heat contained inside the pipe instead of radiating into the engine bay. Cooler intake air means denser charge, and the ceramic finish resists corrosion from road salt, moisture, and heat cycling.
• TIG-welded inside and out - Full penetration welds on the inside of each runner junction reduce turbulence at high RPM. No blow-through welds, no rough seams disrupting exhaust velocity.
• CNC-machined flanges - Precision-machined to resist warping under hard heat cycling, whether that means track days at Laguna Seca or bumper-to-bumper summer commutes.
• Pre-installed factory O2 sensor bung - Direct drop-in for your stock or wideband O2 sensor. No adapters, no chasing threads.
• 50-State C.A.R.B. compliant - EO No. D-370-17 - Fully legal for street use in California and all 49 other states. Run it anywhere.
• Direct bolt-on fitment - Bolts to the stock cylinder head and pairs with any stock or aftermarket cat-back exhaust without modification.

AP1 vs. AP2 Fitment Notes

The HHC5020 is confirmed fitment for the full 2000-2009 production run. The AP1 (2000-2005) uses the 2.0L F20C making 240hp stock, and the AP2 (2006-2009) uses the 2.1L F22C tuned for a broader torque curve. DC Sports engineered the HHC5020 to accommodate both head configurations - same bolt pattern, same O2 bung location, same collector outlet diameter. No fitment adapters required for either generation.

Built for the S2000 Community, Not a Parts Catalog

The S2000 is not a parts-bin car and it does not deserve parts-bin hardware. The HHC5020 is a purpose-built header for one of Honda's most respected platforms - a car that rewards the right modifications with a very direct, mechanical response. The 4-2-1 layout was chosen specifically because the F-Series engine's high-revving nature benefits more from a collector that builds velocity across the mid-range than from a straight-piped 4-1 that only wakes up past 6,000 RPM. We stock this header because it fits, seals properly on the first install, and holds up under real use. That is the only standard we apply.
