Internally, a heavy-duty ceramic honeycomb substrate is coated with an optimized precious-metal catalytic washcoat that rapidly reaches light-off temperatures for efficient HC, CO, and NOx reduction. Integrated mandrel-bent transitions and OE-spec welded mounting flanges match factory hanger points, preventing exhaust leaks without requiring cut-and-clamp fabrication.\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;\"\u003e1996-1998 Chevrolet C\/K Trucks\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;\"\u003eVortec 4.3L (L35) \/ 5.0L (L30) \/ \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;\"\u003e200–230 hp \/ 250–285 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\n\u003cstrong\u003e50275\u003c\/strong\u003e, \u003cstrong\u003e795110\u003c\/strong\u003e, \u003cstrong\u003e9720\u003c\/strong\u003e\n\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 C1500 \/ K1500 (4.3L V6, 5.0L V8)\u003c\/li\u003e\n  \u003cli\u003e1997-1998 Chevrolet C2500 \/ K2500 (5.0L V8 only)\u003c\/li\u003e\n  \u003cli\u003eNote: Fits center position only; not compatible with 5.7L V8 configurations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT400 C\/K Trucks?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for 1996-1998 Chevrolet C\/K Trucks equipped with the \u003cstrong\u003eVortec 4300 L35\u003c\/strong\u003e or \u003cstrong\u003eVortec 5000 L30\u003c\/strong\u003e engine in the center exhaust location.\u003c\/p\u003e\n\n\u003ch4\u003eIs this unit legal for use in CARB-regulated states?\u003c\/h4\u003e\n\u003cp\u003eThis is an EPA-compliant 46-state legal converter and cannot be legally sold or shipped to California, New York, Colorado, or Maine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for the real-world demands of truck duty, this replacement exhaust assembly withstands heavy trailering cycles and high exhaust gas pressures to keep your powertrain running clean and unchoked.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67538077843704,"sku":"DS-EAC4DRKAO","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-chevrolet-c-k-trucks-1996-1998-4-3l-5-0l-center-1.jpg?v=1790622295","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-chevrolet-c-k-trucks-1996-1998-4-3l-5-0l-center","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
