Over time, internal washcoat sintering, carbon contamination, and severe thermal shock lead to ceramic substrate breakdown. This results in reduced exhaust velocity, downstream restriction, and persistent P0420 catalytic efficiency DTCs that trigger limp modes and fail state emissions testing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from corrosion-resistant tubular stainless steel, this assembly matches factory geometry to preserve backpressure balance. Internally, a high-efficiency ceramic honeycomb monolith coated with precious metal catalysts provides complete HC, CO, and NOx scrubbing to comply with OBD standards. Heavy-gauge precision laser-cut flanges and factory O2 sensor bung positioning prevent thermal warping, eliminate exhaust gas leaks, and maintain closed-loop air-fuel feedback accuracy without custom fabrication.\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;\"\u003e2015-2016 Dodge Dart\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;\"\u003e2.4L Tigershark MultiAir II \/ PF Chassis\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;\"\u003e184 hp \/ 174 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;\"\u003eBER638250 (Interchange: 641586, 20479, EC20479)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015 Dodge Dart 2.4L L4 (All trims including GT, Limited, SXT)\u003c\/li\u003e\n  \u003cli\u003e2016 Dodge Dart 2.4L L4 (All trims including GT, Limited, SXT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Dodge Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to clear factory crossmembers and resolve recurring check engine lights, this manifold catalyst restores peak naturally aspirated throttle response and emissions compliance on the PF platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489314246904,"sku":"DS-EWQ4VS5XS","price":198.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-dodge-dart-2015-2016-2-4l-1.jpg?v=1789159748","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-dodge-dart-2015-2016-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
