Constant thermal expansion cycles, engine movement, and vibrational stress cause micro-fissures around the runner merge collector and upper flange. Concurrently, high-mileage washcoat degradation and ceramic substrate attrition trigger recurring check engine lights (DTC P0420), unmetered exhaust leaks, skewed pre-catalyst O2 sensor signals, and failed state emissions inspections.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct replacement for OE part number \u003cstrong\u003eMR299372\u003c\/strong\u003e, this unit integrates heavy-duty cast\/tubular construction reinforced with precise, robotic TIG welds designed to mitigate stress-induced cracking. The internal ceramic substrate features a high-density cell matrix loaded with an advanced precious metal washcoat to efficiently oxidize unburned hydrocarbons and carbon monoxide into inert emissions. Thick, precision-machined mating flanges resist warping under sustained exhaust gas temperatures, while pre-threaded oxygen sensor bungs maintain factory wiring harness geometry without modification.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2002-2003 Mitsubishi Lancer\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\u003e4G94\u003c\/strong\u003e (2.0L SOHC) \/ \u003cstrong\u003eCS6A\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;\"\u003e120 hp \/ 130 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;\"\u003e\n\u003cstrong\u003eMR299372\u003c\/strong\u003e, \u003cstrong\u003e674-848\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002 Mitsubishi Lancer ES (2.0L L4 - 4G94)\u003c\/li\u003e\n  \u003cli\u003e2002 Mitsubishi Lancer LS (2.0L L4 - 4G94)\u003c\/li\u003e\n  \u003cli\u003e2002 Mitsubishi Lancer OZ Rally (2.0L L4 - 4G94)\u003c\/li\u003e\n  \u003cli\u003e2003 Mitsubishi Lancer ES (2.0L L4 - 4G94)\u003c\/li\u003e\n  \u003cli\u003e2003 Mitsubishi Lancer LS (2.0L L4 - 4G94)\u003c\/li\u003e\n  \u003cli\u003e2003 Mitsubishi Lancer OZ Rally (2.0L L4 - 4G94)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the CS6A Lancer?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2003 Mitsubishi Lancer equipped with the 4G94 engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill this direct-fit unit clear an active P0420 fault code?\u003c\/h4\u003e\n\u003cp\u003eYes, replacing an exhausted factory catalyst with this fresh high-efficiency substrate restores catalyst oxygen storage capacity and eliminates the P0420 code once drive cycles are completed.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mitsubishi Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned to preserve proper scavenging velocities across the 4G94 powerband, this manifold ensures factory exhaust acoustic suppression and reliable daily performance for your sport compact platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537785487608,"sku":"DS-E2LJDO7GA","price":116.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-mitsubishi-lancer-2002-2003-2-0l-front-1.jpg?v=1790617544","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-mitsubishi-lancer-2002-2003-2-0l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
