Over time, thermal fatigue causes the factory washcoat to break down, sintering the precious metal loading and sintering the internal monolith. This deterioration leads to core fracture, restricted exhaust flow, elevated backpressure, sluggish high-RPM throttle response, and persistent downstream oxygen sensor catalyst efficiency codes (P0420 bank 1, P0430 bank 2).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit dual-bank catalytic converter assembly utilizes heavy-gauge, corrosion-resistant \u003cstrong\u003e409 stainless steel\u003c\/strong\u003e tubing precision-formed to match factory routing. High-efficiency, thermal shock-resistant ceramic honeycomb substrates are loaded with an optimized precious metal washcoat to provide rapid light-off and reliable hydrocarbon, carbon monoxide, and NOx conversion without choking exhaust velocity. Integrated thick-gauge mounting flanges ensure leak-free seal integrity under high thermal load, mating directly to factory downpipes and exhaust manifolds without cutting or custom welding. Factory-located oxygen sensor bungs maintain proper sensor depth and exposure for accurate closed-loop fuel management.\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;\"\u003e2006-2012 Mitsubishi Eclipse\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\u003e6G75\u003c\/strong\u003e 3.8L V6 \/ \u003cstrong\u003eDK4A\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;\"\u003e263 hp \/ 260 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;\"\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\u003e2006-2012 Mitsubishi Eclipse GT 3.8L V6 (Coupe)\u003c\/li\u003e\n  \u003cli\u003e2007-2012 Mitsubishi Eclipse GT 3.8L V6 (Spyder Convertible)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the DK4A Eclipse?\u003c\/strong\u003e\u003cbr\u003e Yes, this assembly is engineered as a direct replacement for the 2006-2012 Mitsubishi Eclipse equipped with the transverse \u003cstrong\u003e6G75\u003c\/strong\u003e 3.8L V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this converter assembly turn off catalyst efficiency codes like P0420 and P0430?\u003c\/strong\u003e\u003cbr\u003e Yes, the washcoat loading and high-density ceramic substrate restore factory emissions reduction thresholds, clearing catalytic efficiency DTCs assuming upstream air-fuel mixtures and oxygen sensors are operating within specification.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mitsubishi JDM Performance Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve the distinct, aggressive exhaust note and high-rpm breathing characteristics of the 3.8L MIVEC platform while keeping emissions systems fully functional and inspection-ready.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501766021368,"sku":"DS-E5PAYAWJ3","price":461.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-mitsubishi-eclipse-2006-2012-3-8l-left-right-1.jpg?v=1789332245","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-mitsubishi-eclipse-2006-2012-3-8l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
