Heat cycling degrades the original precious-metal washcoat, causing catalytic inefficiency, elevated tailpipe emissions, and persistent P0420\/P0430 DTCs. In severe cases, crumbling ceramic substrates cause structural blockages that generate excessive exhaust backpressure, robbing engine efficiency and increasing thermal stress on the cylinder heads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eManufactured as a direct bolt-on solution for the \u003cstrong\u003eXV30\u003c\/strong\u003e chassis, this left and right bank catalytic converter pair features high-grade stainless steel shell and tube construction for oxidation resistance and structural stability. The internal high-flow ceramic substrate is treated with an OE-grade noble metal washcoat to restore factory-level exhaust gas reduction. Integrated CNC-machined mounting flanges and factory-positioned O2 sensor bungs eliminate the need for cutting, custom fabrication, or re-routing harness wires.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 × Direct-Fit Catalytic Converters (Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003eInstallation Hardware and Gasket Accessories\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;\"\u003e2004-2006 Lexus ES\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;\"\u003e3MZ-FE 3.3L V6 \/ XV30\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;\"\u003e225 hp \/ 240 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;\"\u003e8H52-13\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\u003e2004 Lexus ES330 3.3L V6 (Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003e2005 Lexus ES330 3.3L V6 (Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003e2006 Lexus ES330 3.3L V6 (Left \u0026amp; Right)\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 XV30 ES?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2006 Lexus ES equipped with the \u003cstrong\u003e3MZ-FE\u003c\/strong\u003e 3.3L V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eAre these converters legal in California or CARB-compliant states?\u003c\/h4\u003e\n\u003cp\u003eNo, this EPA-compliant 46-state kit is not legal for sale or use in California, New York, Colorado, or Maine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lexus Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eRestoring emissions performance on your Lexus \u003cstrong\u003e3MZ-FE\u003c\/strong\u003e platform ensures precise air-fuel monitoring, complete diagnostic system readiness, and quiet, factory-grade exhaust acoustics.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67916456526072,"sku":"DS-EATD3DMKG","price":255.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-lexus-es330-2004-2006-3-3l-left-right-1.jpg?v=1793475894","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-lexus-es330-2004-2006-3-3l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
