Over time, restricted internal passages choke exhaust flow from the \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e V8, spiking cylinder head temperatures and triggering persistent P0420 and P0430 diagnostic trouble codes. Furthermore, aging OEM flange joints routinely suffer thermal fatigue, leading to pre-converter leaks that corrupt downstream oxygen sensor readings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from heavy-gauge stainless steel tubing, this direct-fit catalytic converter pair features high-density ceramic honeycomb monoliths engineered with an optimized precious-metal washcoat to maximize catalytic conversion without choking exhaust velocity. Thick, laser-machined mating flanges prevent warpage under sustained exhaust gas temperatures (EGTs), lining up precisely with factory manifold studs and downstream intermediate pipes. The system includes fresh sealing gaskets and installation hardware to ensure a true bolt-on, leak-free mechanical seal without custom welding or 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;\"\u003e2005-2006 Toyota Tundra\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 (4.7L V8) \/ \u003cstrong\u003eXK30 \/ XK40\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;\"\u003e271 hp \/ 313 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\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005-2006 Toyota Tundra Base 4.7L V8\u003c\/li\u003e\n  \u003cli\u003e2005-2006 Toyota Tundra SR5 4.7L V8 (Regular Cab, Access Cab, Double Cab)\u003c\/li\u003e\n  \u003cli\u003e2005-2006 Toyota Tundra Limited 4.7L V8 (Access Cab, Double Cab)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the XK30 \/ XK40 Tundra?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2005-2006 Toyota Tundra equipped with the \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e 4.7L V8 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this resolve P0420 and P0430 DTC codes?\u003c\/strong\u003e\u003cbr\u003e Yes, when paired with operational O2 sensors and a properly running fuel system, the high-efficiency substrate restores catalyst threshold performance to clear emissions codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Truck Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained high-load towing and harsh off-pavement vibration, this direct replacement exhaust assembly provides the thermal durability and structural integrity required for working trucks.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501664801016,"sku":"DS-EJKU593VN","price":169.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-toyota-tundra-2005-2006-4-7l-left-right-1.jpg?v=1789329282","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-toyota-tundra-2005-2006-4-7l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
