DC Sports Ceramic Header for 02-06 RSX / 02-05 Civic Si – SKU: AHC6515

Let your K-series actually breathe. The DC Sports Ceramic Header for 02 RSX / 06 RSX and 02-05 Civic Si (EP3) replaces the factory Civic Si exhaust manifold/RSX manifold with a true 4-1, equal-length layout. It moves exhaust out of the head faster and cleaner, right in the RPM range where VTEC actually does work.


Why it works

  • Real power you can feel – A larger 2.5" collector and smooth mandrel bends let this Acura RSX 4-1 header and Civic Si 4-1 header pick up horsepower and torque throughout the curve. Not just a peak number for a dyno sheet, but stronger midrange and better pull past 6,000 rpm.
  • Ceramic that actually does its job – The thick white coating on this DC Sports ceramic header holds in heat and shrugs off 1200 °F, so under-hood temps stay down and your hoses, wiring, and intake charge stay happier. Less heat soak, more consistent power on hard drives.
  • Built for people who drive hard – T-409 stainless construction with TIG-welded joints and thick, CNC-machined flanges give this RSX performance exhaust header the backbone to handle years of high-RPM abuse without warping or leaking.
  • 50-state legal – This DC Sports Acura exhaust part carries a C.A.R.B. EO, so you can daily it, smog it, and still hammer on it. No “swap it for stock at inspection” nonsense.
  • Bolts up like OEM – This DC Sports 02 Civic header / 05 Civic Si ceramic header / 06 RSX DC Sports header lines up with the factory subframe and exhaust path on 2002-2006 RSX base and 2002-2005 Honda Civic Si DC Sports applications. It mates to the stock B-pipe or most aftermarket cat-backs without drama.

Heard, not just seen

With this DC Sports setup, you’ll get a deeper, crisper tone under load and a cleaner transition into VTEC. No tinny rasp, no highway drone—just that classic K-series bark with more clarity.


Built to stay on the car

Every DC Sports ceramic coated header includes rust-resistant hardware, a high-temp graphite gasket, and an O2 sensor bung so you can bolt it up and forget about it.
