Once internal cell walls fracture, restricted volumetric efficiency creates excessive manifold backpressure, leading to delayed throttle response, reduced torque under load, and recurring check engine lights driven by downstream oxygen sensor cross-counts.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on solution, this front catalytic converter assembly replaces degraded factory emissions components without cutting or custom fabrication. Constructed with a heavy-gauge \u003cstrong\u003eStainless Steel\u003c\/strong\u003e outer shell and mandrel-formed inlet\/outlet routing, it withstands rigorous road shock and thermal expansion. Internally, a high-flow \u003cstrong\u003eCeramic\u003c\/strong\u003e substrate features an optimized washcoat loading of precious catalytic metals (platinum, palladium, and rhodium) to clean raw hydrocarbons (HC) and carbon monoxide (CO) while keeping backpressure low. Precision robotic welding around the mounting brackets and integrated flange junctions ensures leak-free mating with the stock manifold and Y-pipe configuration, maintaining proper sensor bung geometry for factory-correct O2 readings.\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;\"\u003e2005-2006 Dodge Durango\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;\"\u003e3.7L \/ 4.7L PowerTech \/ ND Chassis\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;\"\u003e210 hp \/ 235 lb-ft (3.7L) | 230 hp \/ 290 lb-ft (4.7L)\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;\"\u003eSE20043701\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Dodge Durango 3.7L V6 (Front)\u003c\/li\u003e\n  \u003cli\u003e2006 Dodge Durango 3.7L V6 (Front)\u003c\/li\u003e\n  \u003cli\u003e2005 Dodge Durango 4.7L V8 (Front)\u003c\/li\u003e\n  \u003cli\u003e2006 Dodge Durango 4.7L V8 (Front)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the ND Durango?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2005-2006 Dodge Durango equipped with the PowerTech 3.7L V6 and 4.7L V8 engines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this catalytic converter legal for road use in California?\u003c\/strong\u003e\u003cbr\u003e No, this is an EPA-compliant federal emissions unit and is not legal for sale, installation, or use in California or CARB-restricted states.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Utility Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle severe-duty cycles, heavy payload demands, and continuous highway hauling, this front catalytic assembly ensures your full-size Durango maintains reliable exhaust throughput and emissions compliance under the harshest towing workloads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501752619256,"sku":"DS-EXAIR63XV","price":296.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-dodge-durango-2005-2006-3-7l-4-7l-front-1.jpg?v=1789332118","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-dodge-durango-2005-2006-3-7l-4-7l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
