Under continuous thermal stress and rich-running conditions typical of the \u003cstrong\u003eVG33E\u003c\/strong\u003e, the OEM ceramic cores experience sintered precious metal active sites and internal brick fracture. This failure manifests as catalytic efficiency degradation, triggering persistent Bank 1 and Bank 2 check engine lights (P0420 and P0430). In severe cases, fragmented honeycomb structures create exhaust flow restrictions, generating parasitic backpressure that bogs down mid-range torque, degrades fuel economy, and elevates exhaust gas temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to resolve bank imbalance and flow restrictions, this left-and-right manifold-back set utilizes heavy-gauge 409 stainless steel tubing to resist external oxidation and stress cracks. Inside, a high-density 600 CPSI cordierite ceramic substrate provides exceptional surface area, coated with a durable palladium and rhodium catalytic washcoat to maximize emissions conversion efficiency. Mandrel-bent transition sections maintain uniform exhaust gas velocity, eliminating turbulence found in crush-bent piping. Heavy-duty, precision-machined flanges mate flush to the factory exhaust manifolds and downpipes, while OE-positioned O2 sensor bungs allow factory downstream sensors to thread directly without wiring harness extensions or modifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Left (driver side) catalytic converter\u003c\/li\u003e\n  \u003cli\u003e1 Right (passenger side) catalytic converter\u003c\/li\u003e\n  \u003cli\u003eMounting hardware\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: solid font-size: min-width:\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;\"\u003e2000-2001 Nissan Xterra\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;\"\u003eVG33E \/ WD22\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;\"\u003e170 hp \/ 200 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\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000 Nissan Xterra 3.3L V6 (VG33E) Driver and Passenger Side\u003c\/li\u003e\n  \u003cli\u003e2001 Nissan Xterra 3.3L V6 (VG33E) Driver and Passenger Side\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 WD22 Xterra?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2000-2001 Nissan Xterra equipped with the \u003cstrong\u003eVG33E\u003c\/strong\u003e engine. \u003cstrong\u003eNote: This system is 49-state Federal OBD-II compliant and is not legal for sale or use in California, Colorado, New York, or Maine.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eAre cutting or welding operations required during installation?\u003c\/h4\u003e\n\u003cp\u003eNo, this assembly features a direct-fit, bolt-on layout designed to mate directly with existing factory exhaust components using the included hardware.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Truck Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe trail washboards and demanding payload cycles, this assembly provides rugged structural durability and OEM-grade flow characteristics to keep your utility rig running clean across backroads and highways.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67901430890744,"sku":"DS-E6Z4F7HV6","price":114.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-nissan-xterra-2000-2001-3-3l-left-right-1.jpg?v=1793336198","url":"https:\/\/performancechiptuning.com\/de\/products\/catalytic-converter-for-nissan-xterra-2000-2001-3-3l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
