Over time, the internal OEM ceramic honeycomb matrix fractures or suffers washcoat depletion, leading to restricted exhaust backpressure, lost low-end torque, and catalyst efficiency failure codes. Furthermore, factory mild-steel flange points frequently suffer from surface corrosion and warping, yielding post-manifold exhaust leaks.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed with a heavy-gauge stainless steel outer shell and a high-flow ceramic substrate, this direct-fit unit withstands severe thermal shock while maintaining proper precious metal catalytic reduction. Features include mandrel-bent stainless tubing for smooth exhaust velocity, precision CNC-machined mounting flanges, automated TIG welding, and a perforated heat shield to protect adjacent chassis components. Comes complete with a pre-welded oxygen sensor bung, replacement gaskets, and installation hardware for a true bolt-on repair.\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;\"\u003e2005-2012 Nissan Pathfinder (Driver Side)\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;\"\u003e4.0L VQ40DE V6 \/ R51 Platform\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;\"\u003e266 hp \/ 288 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;\"\u003eOEMCONV017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVehicle:\u003c\/strong\u003e 2005-2012 Nissan Pathfinder (4.0L V6)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Driver Side (Bank 2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEmissions Standard:\u003c\/strong\u003e EPA OBD-II Approved (Federal 49-State).
