DC Sports Stainless Header for 04-08 Acura TSX
Breathe new life into your K24-powered sedan with the DC Sports ceramic-coated header engineered for 04-08 Acura TSX applications. This 4-2-1, two-piece design utilizes race-bred, equal-length 304 stainless steel runners that step up from stock diameter to clear exhaust congestion, resulting in a crisper throttle response, a fatter mid-range torque curve, and gains you can feel all the way to redline. A true street performer, the header carries CARB EO# D-370-14 for 2004-2007 models, keeping you emissions-legal in all 50 states while still unlocking horsepower. Precision CNC-machined flanges prevent warping and pair with the direct bolt-in fitment to mate flawlessly with the factory catalytic converter and exhaust. No O2 extension harnesses, cut pipes, or band-aid gaskets required.
Optional Ceramic Coating Finish
Add the optional high-temperature ceramic coating, rated for up to 1,200°F, to keep exhaust heat where it belongs, inside the pipes. By holding heat in, exhaust gases move faster, helping the engine breathe better and make more consistent power. It also reduces the heat radiating into the engine bay, keeping intake temperatures cooler and everything under the hood happier. The coating withstands endless heat cycles, helping the header maintain its clean finish.
Why it belongs on your TSX
