DC Sports K Swap 4-2-1 Header

DC Sports K Swap 4-2-1 Header - EG/EK/DC/Del Sol

The DC Sports K Swap 4-2-1 Header is the perfect performance upgrade for your K-swapped project. Designed to fit 1992-2000 Honda Civics, 1993-1997 Honda Del Sol, and 1994-2001 Acura Integras, this header is built specifically for K20 and K24 engine swaps using Hasport or Innovative mount kits. Whether you're running Hasport mounts at standard or raised height, or using the furthest-forward position on your Innovative mounts, this header fits with no issues. Designed to work with EG and DC subframes, the EK Civic subframe will need to be switched to avoid fitment issues. 

Constructed from high-quality 304 stainless steel, the DC Sports 4-2-1 header delivers reliable power and long-lasting durability. The one-piece design improves exhaust flow and simplifies installation. This header comes complete with a new multi-layer steel (MLS) exhaust manifold gasket, precision-machined flanges, and all necessary hardware—including a donut gasket for a proper exhaust seal.

DC Sports’ 4-2-1 design offers a strong balance of low-end torque and top-end power, making it ideal for both street driving and track days. Unlike universal headers that require modification, this header is purpose-built for K-series engines both Civic and Integra chassis, ensuring proper ground clearance and firewall spacing. That means no guesswork or cutting required—just bolt it up and go. It’s a smart choice for K-swap enthusiasts who want performance and reliability without the hassle.
