Over time, thermal cycling degrades the internal ceramic substrate, while flex fatigue causes pinhole fractures, unmetered air intrusion, false upstream\/downstream O2 sensor voltage readings, and recurring P0420\/P0430 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered with computerized mandrel-bent stainless steel piping, this assembly maintains uniform internal diameter to eliminate backpressure restrictions and promote laminar exhaust scavenging. It features a heavy-duty double-braided flex joint that absorbs engine vibration without cracking, paired with an OBD-II compliant high-grade ceramic catalyst substrate designed to restore OE flow dynamics and exhaust thermal efficiency.\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;\"\u003e2002-2005 Nissan Altima\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;\"\u003e3.5L VQ35DE \/ L31\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;\"\u003e240-250 hp \/ 246-249 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;\"\u003e324204, 54478, 0991402\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2005 Nissan Altima SE 3.5L V6 (Automatic \u0026amp; Manual Transmissions)\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Nissan Altima SL 3.5L V6 (Automatic \u0026amp; Manual Transmissions)\u003c\/li\u003e\n  \u003cli\u003e2005 Nissan Altima SE-R 3.5L V6 (Automatic \u0026amp; Manual Transmissions)\u003c\/li\u003e\n  \u003cli\u003eFits EPA OBD-II Federal Emissions models only (Not legal for sale\/use in CA, ME, or NY).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan VQ-Series Exhaust Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve the distinct high-flow acoustic profile and smooth throttle response of your VQ35DE power plant with heavy-gauge precision flanges and leak-free hardware integration.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50464286441720,"sku":"DS-EQUUJ6I3X","price":134.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-nissan-altima-2002-2005-3-5l-1.jpg?v=1788878929","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-nissan-altima-2002-2005-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
