Over decades of thermal cycling, these heavy factory manifolds are prone to heat retention, cracking along the collector, and excessive heat soak within the engine bay. The internal surface of the factory cast manifold is rough, creating turbulent airflow that impedes exhaust gas velocity, increases backpressure, and ultimately stifles the engine's volumetric efficiency across the RPM band.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis 2-piece 4-2-1 exhaust header system is engineered to maximize exhaust gas velocity and eliminate the backpressure inherent to the factory setup. Constructed from CNC-machined T-304 stainless steel, the mandrel-bent piping maintains a consistent diameter throughout the primary and secondary tubes. The 4-2-1 design optimizes mid-range torque and high-RPM horsepower by improving the exhaust scavenging effect. Computerized TIG-welded flanges ensure structural integrity and a leak-free seal under extreme thermal stress. Featuring a 1.75-inch inlet and a 2.0-inch outlet, this header smoothly transitions exhaust gases out of the cylinder head. Pre-welded hangers align perfectly with factory mounting points, ensuring a direct bolt-on installation without the need for custom fabrication or cutting.\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1988-2000 Honda Civic\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eD-Series SOHC (D15, D16) \/ EF, EG, EK\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e70-127 hp \/ 83-107 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e1988-1991 Honda CRX (D-Series SOHC Engines Only)\u003c\/li\u003e\n    \u003cli\u003e1993-1997 Honda Del Sol (D-Series SOHC Engines Only)\u003c\/li\u003e\n    \u003cli\u003e1988-2000 Honda Civic (D-Series SOHC Engines Only)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Honda Performance Standard\u003c\/h3\u003e\n  \u003cp\u003eBuilt for the dedicated tuner, this header delivers the crisp exhaust note, enhanced throttle response, and optimized powerband required for naturally aspirated JDM performance builds.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48328122204408,"sku":"DS-E3789CLFZ","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-headers-for-honda-civic-1988-2000-1-5l-1-6l-1.webp?v=1778011925","url":"https:\/\/performancechiptuning.com\/products\/exhaust-headers-for-honda-civic-1988-2000-1-5l-1-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
