Product Details
Improve exhaust flow, mid-range performance, and under-hood heat management with the DC Sports HHS5504 Polished Stainless Steel 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.
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.
