In the 5.7L applications, this deterioration creates severe exhaust backpressure, choking top-end power output, driving up exhaust gas temperatures, and tripping OBD-II trouble codes such as P0420 and P0430 under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement assembly utilizes a high-flow ceramic honeycomb substrate coated with a high-grade precious metal washcoat to rapidly convert HC, CO, and NOx emissions without bottlenecking cylinder scavenging. Constructed with a heavy-gauge stainless steel outer shell and aluminized tubing, the unit resists road de-icer corrosion and thermal expansion cracks. Robotically welded flanges and pre-positioned O2 sensor bungs mirror the OEM configuration, allowing seamless bolt-in replacement without cutting or custom pipe expansion.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Direct-Fit Catalytic Converter Assembly\u003c\/li\u003e\n  \u003cli\u003e1x Installation Accessory Kit\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;\"\u003e1996-1998 Chevrolet Suburban\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\u003eVortec 5700 L31\u003c\/strong\u003e \/ \u003cstrong\u003eGMT400\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;\"\u003e250 hp \/ 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;\"\u003e\u003cstrong\u003e795110\u003c\/strong\u003e\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\u003e1996-1998 Chevrolet Suburban C1500 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e1996-1998 Chevrolet Suburban K1500 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e1996-1998 Chevrolet Suburban C2500 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e1996-1998 Chevrolet Suburban K2500 5.7L V8\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 GMT400 Suburban?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1996-1998 Chevrolet Suburban equipped with the \u003cstrong\u003eVortec 5700 L31\u003c\/strong\u003e engine. \u003cstrong\u003eRestricted: Cannot ship to or be operated in California, New York, Colorado, or Maine (EPA 46\/49-state legal only).\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWill this require welding or aftermarket ECU tuning?\u003c\/h4\u003e\n\u003cp\u003eNo, this unit installs into the factory exhaust hangers using stock mounting points and retains OE-spec OBD-II closed-loop catalyst monitoring.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Towing Caliber\u003c\/h3\u003e\n\u003cp\u003eDesigned to maintain full towing capacity and heavy payload reliability, this direct-fit converter restores low-end torque delivery and thermal stability across demanding haul cycles on your \u003cstrong\u003eGMT400\u003c\/strong\u003e chassis.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67915596595448,"sku":"DS-EN6RMV56X","price":201.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-chevrolet-suburban-1996-1998-5-7l-1.jpg?v=1793466620","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-chevrolet-suburban-1996-1998-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
