Improve exhaust flow, mid-range performance, and under-hood heat management with the DC Sports HHC5504 Ceramic-Coated 4-2-1 Header. Designed specifically for the 1999–2000 Honda Civic Si and 1994–1997 Honda Del Sol VTEC, this performance header is engineered around the B16A2 and B16A3 DOHC VTEC engines. DC Sports currently lists HHC5504 as the ceramic-coated version of its header for these applications.
The HHC5504 features a one-piece 4-2-1 configuration with equal-length primary runners. This design promotes efficient exhaust scavenging and is tuned to provide a broad, usable powerband with an emphasis on mid-range horsepower and torque—making it an excellent choice for street-driven and naturally aspirated B-Series builds.
Constructed from T409 stainless-steel tubing, the header uses mandrel-bent runners, CNC-machined flanges, and TIG-welded joints for strength and consistent exhaust flow. A high-temperature ceramic coating helps reduce radiant heat in the engine compartment while protecting the header from harsh operating conditions.

Ceramic-Coated Performance
- The ceramic finish is one of the key advantages of the HHC5504. By reducing the amount of radiant heat released from the header tubing, the coating helps control engine-bay temperatures while also providing additional protection for the underlying stainless steel. DC Sports' ceramic coating is rated to withstand temperatures up to approximately 1,200°F.
DC Sports currently offers this header application in two finishes:
- HHC5504 – Ceramic Coated
- HHS5504 – Stainless Steel
Both are designed for the 1999–2000 Civic Si and 1994–1997 Del Sol VTEC, while the HHC5504 adds the thermal-management benefits of the ceramic coating.
Emissions Compliance
- The DC Sports HHC5504 is listed as 50-state CARB compliant under Executive Order D-370-14, making it a particularly attractive option for enthusiasts who want a performance header while retaining emissions compliance for the applications covered by the exemption.
The DC Sports HHC5504 Ceramic-Coated 4-2-1 Header is an excellent upgrade for B16-powered Civic Si and Del Sol VTEC owners looking for a combination of improved exhaust flow, stronger mid-range performance, reduced under-hood heat, direct-fit installation, and classic DC Sports B-Series performance.
