PRODUCT DETAILS

DC Sports Ceramic Header for 02-06 RSX/02-05 Civic Si

Unlock the real voice of your K-series. The DC Sports Ceramic Header for 02-06 RSX/02-05 Civic Si replaces the factory log manifold with a true 4-1, equal-length design that evacuates exhaust gases faster and cleaner—right where VTEC loves to live.


Why it works

  • Dyno-proven power gains – larger-than-stock 2.5" collector and smooth mandrel bends free up horsepower and torque across the entire rev range, not just at peak.
  • Cooler, cleaner engine bay – thick, white ceramic coating blocks radiant heat and withstands 1200 °F, lowering under-hood temps and protecting hoses, wiring, and your intake charge.
  • Hand-built for racers – TIG-welded inside and out from T-409 stainless steel with CNC-machined flanges that won’t warp or leak, even after years of high-RPM abuse.
  • 50-state street legal – C.A.R.B. EO-approved, so you can daily drive it, smog it, and still romp on it without worrying about tickets.
  • Direct bolt-on fit – designed around the OEM sub-frame and exhaust location for the 2002-2006 Acura RSX base and 2002-2005 Honda Civic Si (EP3); mates to factory or aftermarket B-pipe.

Heard, not just seen

Expect a deeper, sharper exhaust note under load and a smoother transition into i-VTEC—no rasp, no drone, just clean K-series bark.


Built to outlast your build

Rust-resistant hardware, high-temp graphite gasket, and O2 sensor bung are included so you can install once and drive hard, worry-free.
