Unburned hydrocarbons and thermal fatigue foul the OEM substrate, triggering persistent diagnostic trouble codes such as \u003cstrong\u003eP0420\u003c\/strong\u003e (Bank 1) and \u003cstrong\u003eP0430\u003c\/strong\u003e (Bank 2). A clogged or rattling ceramic matrix also generates severe exhaust backpressure, choking cylinder scavenging on the \u003cstrong\u003eVG33E\u003c\/strong\u003e engine, which degrades fuel economy, blunts throttle response, and elevates cylinder head temperatures under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement assembly provides a dual-bank solution engineered to restore federal emissions compliance and factory exhaust velocity. Fabricated with heavy-gauge \u003cstrong\u003e409 stainless steel\u003c\/strong\u003e outer canisters, the units house high-density 600 CPSI cordierite ceramic substrates loaded with a balanced palladium and rhodium wash coat for efficient catalytic conversion. Smooth, mandrel-bent inlet and outlet sections minimize turbulence, while precision-machined flanges mate cleanly with OEM manifolds and downstream intermediate piping. Pre-welded oxygen sensor bungs occupy exact factory locations to ensure seamless reinstallation of stock upstream and downstream O2 sensors without harness 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: 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;\"\u003e1999-2001 Nissan Frontier\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 \/ D22\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\u003e1999 Nissan Frontier 3.3L V6 (VG33E)\u003c\/li\u003e\n  \u003cli\u003e2000 Nissan Frontier 3.3L V6 (VG33E)\u003c\/li\u003e\n  \u003cli\u003e2001 Nissan Frontier 3.3L V6 (VG33E)\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 D22 Frontier?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1999-2001 Nissan Frontier equipped with the \u003cstrong\u003eVG33E\u003c\/strong\u003e 3.3L V6 engine. \u003cstrong\u003eThis part is not legal for sale or use in California, Colorado, New York, or Maine on CARB-governed emissions vehicles.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWill this converter set resolve P0420 and P0430 fault codes?\u003c\/h4\u003e\n\u003cp\u003eProvided there are no underlying upstream issues such as unmetered air leaks, misfires, or faulty oxygen sensors, the active palladium and rhodium substrate will restore converter efficiency and resolve catalyst-related DTCs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Frontier Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for working trucks, this bolt-on exhaust solution delivers reliable backpressure management to protect your low-end torque curves when towing, hauling payloads, or logging extended highway mileage.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67901429317880,"sku":"DS-E3NYMD8A9","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-frontier-1999-2001-3-3l-left-right-1.jpg?v=1793336148","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-nissan-frontier-1999-2001-3-3l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
