Sustained operating temperatures and carbon accumulation break down the internal ceramic substrate, causing cell collapse, increased backpressure, degraded fuel trim efficiency, and persistent check engine lights. In severe cases, disintegrating substrate material risks migrating upstream during valve overlap, creating severe mechanical hazards for the engine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement converter pipe features a heavy-duty stainless steel casing paired with a high-efficiency washcoat ceramic honeycomb core to ensure rapid light-off and optimal catalyst surface area. Built with mandrel-bent stainless steel tubing, precision TIG welds, and thick OE-spec flanges, it matches factory exhaust geometry perfectly to prevent exhaust leaks and eliminate mechanical stress at the connection points.\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;\"\u003e2004-2006 Nissan Maxima\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;\"\u003eVQ35DE \/ A34\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;\"\u003e265 hp \/ 255 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;\"\u003eOEMCONV038 \/ 40576\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Nissan Maxima 3.5L V6 Automatic (SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2005 Nissan Maxima 3.5L V6 Automatic (SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2006 Nissan Maxima 3.5L V6 Automatic (SE, SL)\u003c\/li\u003e\n  \u003cli\u003eEPA OBD-II Approved for Federal 49-State Use (Not legal for sale or use in CA, NY, or ME)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan VQ Platform Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to restore factory exhaust velocity, throttle response, and the signature clean VQ35DE exhaust note while ensuring trouble-free OBD-II monitor readiness.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50462759485688,"sku":"DS-EA1SCNO18","price":119.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-nissan-maxima-2004-2006-3-5l-1.jpg?v=1788844016","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-nissan-maxima-2004-2006-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
