Show original supplier description

The DC Sports HHS5613 Stainless Steel Header is a performance upgrade engineered to replace the restrictive stock cast manifold on 1992-2000 Honda Civic and 1993-1997 Honda Del Sol Si models. Featuring a 4-1 long-tube, equal-length runner design, this header utilizes mandrel-bent 304 stainless steel tubing to significantly increase exhaust flow, leading to sharper throttle response and noticeable power gains across the entire RPM range, particularly improving midrange performance. Constructed with precision, the header boasts CNC-machined 3/8" flanges designed for a flat, leak-free seal that resists warping. The 4-1 merge collector is optimized for strong, usable power from low RPM to redline. This header is 50-state legal, carrying C.A.R.B. EO# D-370-14 for specified 1.5L & 1.6L trims, ensuring compliance with emissions regulations. Unlike some performance parts, the HHS5613 is designed to retain essential comfort and convenience features, including A/C and power steering, making it suitable for daily driving. Users can typically expect real-world gains of 8-12 horsepower at the wheels, accompanied by a deeper, crisper exhaust note without excessive highway drone. The product is available in either a polished stainless steel finish (HHS5613) or a high-temperature ceramic coating (HHC5613), which can reduce under-hood temperatures and improve exhaust gas velocity. The installation process is supported by an available install guide.
