DC Sports Header for 99-00 Civic Si/94-97 Del Sol VTEC

DC Sports Headers for 99–00 Civic Si & 94–97 Del Sol VTEC (B16)

If you’re hunting for a legit performance bump from your B-series without trashing drivability, this DC Sports 4-2-1 header is the move. Built for the 1999–2000 Civic Si and 1994–1997 Del Sol VTEC, this header uses a DC Sports 4-2-1 header layout with equal-length primaries and smooth mandrel bends to help the motor breathe the way it should.

On a healthy B16, you’ll typically see 8–12 whp with a proper exhaust header like this—spread across the whole rev range. No “one big number at 8,500 and nothing everywhere else” nonsense. You’ll feel sharper throttle response and stronger midrange from about 3,000 rpm to redline. Thick CNC‑machined flanges fight warping, and the TIG‑welded 304 stainless construction holds up to abuse and daily use. It also carries a C.A.R.B. EO number, so your ceramic header setup stays 50‑state legal while you actually enjoy the car.

Header Finish Options

SKU: HHS5504 | Header Finish: Stainless Steel
The straight stainless header option gives you the classic header: raw 304 stainless, strong welds, and solid heat resistance. It’s a clean, durable upgrade if you want performance without the extra thermal control of ceramic.

SKU: HHC5504 | Header Finish: Ceramic Coated
Step up to the ceramic header version if you care about heat management. The coating is rated to 1,200°F and keeps more heat inside the tubes, which keeps exhaust gas velocity up and helps the engine stay consistent on back‑to‑back pulls or long track sessions. You’ll also see lower under‑hood temps—better for intake temps, wiring, and anything plastic near the manifold. The ceramic finish takes repeated heat cycles without flaking when you treat it like a performance part, not a showpiece.

Key Benefits

• Direct bolt‑on for B16A2/B16A3 in EM1 Civic Si and Del Sol VTEC—no cutting, no extra brackets
• DC Sports 4-2-1 header layout gives a fatter torque curve than a typical 4‑1 race header, especially in the midrange where you actually drive
• Ceramic‑coated versions help cut radiant heat and keep power more consistent on hot days and long pulls
• Factory O₂ bung and gasket locations line up, so the Civic Si stainless header / Del Sol stainless header drops in without drama
• Includes hardware and collector gasket; bolts up to stock or aftermarket cat‑back exhausts without weird adapters

This DC Sports header is for people who actually drive their cars—daily, canyon, or track—who want real gains, not noise and heat soak. We run these same Civic Si VTEC header and Del Sol VTEC header setups on our own B‑series cars and beat on them regularly.
