Over extended mileage, the original ceramic honeycomb matrices suffer thermal shock, precious metal depletion, and carbon fouling. This breakdown triggers diagnostic trouble codes P0420 and P0430. Worse, degrading core structures can fracture, causing internal rattling, increased exhaust backpressure, lost fuel economy, and the potential for abrasive substrate dust to be drawn back into the combustion chambers during valve overlap.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete three-piece catalytic converter package features durable, heat-resistant 409 stainless steel outer shells and smooth, mandrel-bent inlet and outlet piping. Each converter houses a high-efficiency 600 CPSI cordierite ceramic substrate layered with a precise palladium-rhodium washcoat formulation, engineered for rapid light-off times and complete emissions conversion. Thick, precision-machined mating flanges prevent thermal warping and exhaust gas leaks, while factory-located O2 sensor bungs allow factory lambda probes to thread directly into place without harness alterations or extensions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Front Left (Radiator Side) Manifold Catalytic Converter\u003c\/li\u003e\n  \u003cli\u003e1x Front Right (Firewall Side) Manifold Catalytic Converter\u003c\/li\u003e\n  \u003cli\u003e1x Rear Underfloor Catalytic Converter\u003c\/li\u003e\n  \u003cli\u003eDirect-fit installation mounting hardware kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2009-2014 Nissan Maxima\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;\"\u003eVQ35DE \/ A35\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;\"\u003e290 hp \/ 261 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\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2014 Nissan Maxima S 3.5L V6 (VQ35DE)\u003c\/li\u003e\n  \u003cli\u003e2009-2014 Nissan Maxima SV 3.5L V6 (VQ35DE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the A35 Maxima?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2014 Nissan Maxima equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e engine.
