Precision-formed direct-replacement mating flanges mate flush to the factory exhaust manifolds and intermediate crossover pipes without cutting or custom fabrication. Integrated heavy-duty O2 sensor bungs eliminate thread galling, while mandrel-bent tubing geometry maintains linear exhaust velocity to maintain rated backpressure characteristics across the entire powerband.\u003c\/p\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;\"\u003e2000-2006 Chevrolet Suburban 1500\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;\"\u003e5.3L Vortec 5300 (LM7\/L59) \/ GMT800\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;\"\u003e285-295 hp \/ 325-335 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;\"\u003e9063, 20370, 51097, 2010019, 50511, 19010, 9083, 50366, 93419, 079-5150\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\u003e2000-2006 Chevrolet Suburban 1500 5.3L V8 (Base, LS, LT, Z71)\u003c\/li\u003e\n  \u003cli\u003eNote: Front placement only; fits 5.3L V8 models, does not fit 6.0L or 8.1L platforms.\u003c\/li\u003e\n  \u003cli\u003eEmissions: 48-state EPA compliant; not legal for sale or use in CA, NY, CO, or ME.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT800 Suburban?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for the 2000-2006 Chevrolet Suburban 1500 equipped with the \u003cstrong\u003e5.3L Vortec (LM7\/L59)\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill this resolve P0420 and P0430 DTC codes?\u003c\/h4\u003e\n\u003cp\u003eYes, renewing failed converters with fresh ceramic washcoat elements brings downstream oxygen sensor readings within factory OBD-II thresholds, resolving catalytic efficiency faults.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the thermal demands of heavy hauling and off-road duty, this converter assembly restores factory exhaust scavenging and keeps your full-size hauler running clean under maximum payload.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67538073125112,"sku":"DS-E0FFGPWAQ","price":202.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-chevrolet-suburban-2000-2006-5-3l-front-1.jpg?v=1790622108","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-chevrolet-suburban-2000-2006-5-3l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
