This thermal exhaustion leads to insufficient exhaust gas reduction, tripping persistent \u003cstrong\u003eP0420\u003c\/strong\u003e and \u003cstrong\u003eP0430\u003c\/strong\u003e diagnostic trouble codes. Concurrently, factory seam welds and pipe junctions corrode and split, leaking unmetered air that distorts oxygen sensor trims and compromises cylinder scavenging.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed specifically for the \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e 4.7L V8 platform, this driver and passenger side assembly features corrosion-resistant stainless steel housings packed with a high-flow ceramic honeycomb matrix. Optimized cell density ensures proper hydrocarbon and carbon monoxide conversion while preserving unhindered exhaust gas velocity. Precision-stamped, direct-fit mounting flanges integrate directly to the OEM manifold studs and mid-pipe flanges, creating a leak-free mechanical seal that eliminates exhaust leaks and restores balanced exhaust backpressure without requiring custom fabrication.\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;\"\u003e2001-2004 Toyota Sequoia\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;\"\u003e\n\u003cstrong\u003e2UZ-FE\u003c\/strong\u003e \/ \u003cstrong\u003eUCK35 \/ UCK45\u003c\/strong\u003e\n\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;\"\u003e240 hp \/ 315 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;\"\u003e\n\u003cstrong\u003e54569\u003c\/strong\u003e, \u003cstrong\u003e55443\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001 Toyota Sequoia SR5 \/ Limited 4.7L V8 (2UZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2002 Toyota Sequoia SR5 \/ Limited 4.7L V8 (2UZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2003 Toyota Sequoia SR5 \/ Limited 4.7L V8 (2UZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2004 Toyota Sequoia SR5 \/ Limited 4.7L V8 (2UZ-FE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the UCK35 \/ UCK45 Sequoia?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2001-2004 Toyota Sequoia equipped with the 2UZ-FE engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this resolve P0420 and P0430 diagnostic fault codes?\u003c\/strong\u003e\u003cbr\u003e Yes, provided upstream fuel delivery and ignition components are functional, this assembly restores emissions efficiency to clear catalyst-related DTCs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Towing Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained thermal stress under heavy payload and trailer pulling, this direct-replacement assembly delivers the structural integrity and emissions performance required to keep your full-size truck working reliably.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50502190137592,"sku":"DS-EGEU1SB4W","price":350.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-toyota-sequoia-2001-2004-4-7l-left-right-1.jpg?v=1789338921","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-toyota-sequoia-2001-2004-4-7l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
