Continuous heat cycling causes structural brittleness, frequently leading to stress fractures along the runner junctions and collector neck. Furthermore, uneven runner lengths and rough interior casting surfaces introduce turbulent backpressure directly against the exhaust ports of the \u003cstrong\u003e4G63\u003c\/strong\u003e naturally aspirated engine, choking exhaust scavenging and compounding heat soak in the cylinder head.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eFabricated from semi-polished mandrel-bent stainless steel, this performance exhaust header eliminates turbulence through smooth, uniform-radius primary tubing. The mandrel-bent design preserves cross-sectional volume throughout every bend, maximizing gas velocity and optimizing pulse pairing for superior scavenging dynamics. Precision-machined, thick-flange interfaces provide a warp-resistant seal against the cylinder head, preventing high-temperature exhaust leaks. By shedding significant weight compared to heavy OEM cast iron and incorporating a dedicated O2 sensor bung, this header delivers a true direct-fit bolt-on solution engineered for high thermal tolerance and sustained power output.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1990-1994 Mitsubishi Eclipse \/ Eagle Talon\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e4G63 (Non-Turbo)\u003c\/strong\u003e \/ \u003cstrong\u003e1G (D21A\/D22A)\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e135 hp \/ 125 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eSPT-EHD1438\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1990 Mitsubishi Eclipse 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1991 Mitsubishi Eclipse 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1992 Mitsubishi Eclipse 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1993 Mitsubishi Eclipse 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1994 Mitsubishi Eclipse 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1990 Eagle Talon 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1991 Eagle Talon 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1992 Eagle Talon 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1993 Eagle Talon 2.0L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1994 Eagle Talon 2.0L Naturally Aspirated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the 1G Eclipse,Talon?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1990-1994 Mitsubishi,Eagle Eclipse,Talon equipped with the \u003cstrong\u003e4G63\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to retorque the manifold hardware after installation?\u003c\/strong\u003e\u003cbr\u003e Yes, you should always heat-cycle the engine to operating temperature and retorque all flange fasteners to prevent gasket blowout.\u003c\/p\u003e\n\n\u003ch3\u003eThe 1G DSM Performance Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered specifically for the iconic Japanese sport compact chassis, this header delivers the crisp, aggressive exhaust note and high-rpm breathing efficiency that vintage DOHC tuners demand.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50606907851000,"sku":"DS-E33H35V6W","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-header-for-mitsubishi-eclipse-eagle-talon-1990-1994-2-0l-1.jpg?v=1790090870","url":"https:\/\/performancechiptuning.com\/fr\/products\/exhaust-header-for-mitsubishi-eclipse-eagle-talon-1990-1994-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
