Oil blow-by or running rich coats the factory honeycomb matrix, triggering recurring P0420 or P0430 DTC catalyst efficiency codes. Eventually, internal ceramic fragmentation leads to severe exhaust backpressure, causing localized heat soak and choking volumetric efficiency across the mid-to-high RPM range on both the naturally aspirated \u003cstrong\u003eVQ35DE\u003c\/strong\u003e and direct-injected \u003cstrong\u003eVQ35DD\u003c\/strong\u003e 3.5L V6 engines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered with a heavy-gauge stainless steel outer shell, this direct-fit rear assembly resists road debris corrosion and thermal fatigue. Inside, a high-efficiency ceramic honeycomb substrate provides optimal precious metal surface loading to support complete exhaust gas redox reactions without restricting scavenging velocity. Precise OE-spec flanges, factory-location mounting brackets, and included hardware ensure drop-in alignment to OEM intermediate pipes without torching, cutting, or fabrication. This assembly, designated by part reference \u003cstrong\u003eSM20133501\u003c\/strong\u003e, provides a secure, leak-free seal that prevents false downstream oxygen sensor 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;\"\u003e2013-2019 Nissan Pathfinder\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;\"\u003e3.5L VQ35DE \/ VQ35DD \/ R52\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;\"\u003e260-284 hp \/ 240-259 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;\"\u003eSM20133501\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013-2019 Nissan Pathfinder S 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2013-2019 Nissan Pathfinder SV 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2013-2019 Nissan Pathfinder SL 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2013-2019 Nissan Pathfinder Platinum 3.5L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the R52 Pathfinder?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2013-2019 Nissan Pathfinder equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e and \u003cstrong\u003eVQ35DD\u003c\/strong\u003e 3.5L engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this resolve catalyst efficiency DTCs like P0420?\u003c\/strong\u003e\u003cbr\u003e Assuming fuel delivery and oxygen sensors are working properly, this converter restores emissions efficiency to clear catalytic threshold trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the constant thermal loads of family transport and up to 5,000 lbs of towing duty, this catalytic converter restores factory backpressure targets and mechanical durability for the long haul.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501716345080,"sku":"DS-E1A4MBIPE","price":219.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-nissan-pathfinder-2013-2019-3-5l-rear-1.jpg?v=1789330691","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-nissan-pathfinder-2013-2019-3-5l-rear","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
